1795 Half Cent – Double Error in Heritage Auction

1795 Half Cent Double ErrorWhen reviewing upcoming auctions, one of the things we like to look for are the more unusual items, the coins that surprise you and say “I didn’t know that!”

In the upcoming Heritage Signature Sale of The Ellsworth Collection (May 29th) we found the following 1795 Double Error Half Cent.

Below is the auction catalog Description:

This is a stunning and spectacular double error, either of which would be extremely important in its own right. The substantial curved clip is positioned at 4 o’clock. This clip is larger than any we recall seeing on a half cent of any date, let alone this 18th century date. Similarly, the off-center strike, positioned to 9 o’clock, is further off-center than we recall on any other examples. The combination is nothing short of amazing.

Any combination of two or more error types on a single coin essentially makes that coin unique. It is completely unreasonable to think that another identical error combination could have been produced, unless someone at the Mint was making these intentionally, and during the 1790s, that was probably not the case.

The surfaces are lightly corroded. The obverse has charcoal-brown and deep green color, with mostly deep green on the reverse. A few old obverse scratches are so nicely blended with the rest of the coin that they are not immediately obvious. EAC 12.

PCGS Guidance – Sacagawea Cheerios Dollars

Cheerios Original packagingAs part of an effort in 1999 to promote the new Sacagawea Dollars, General Mills scattered 5,500 specially-packaged 2000-dated Sacagawea Dollars among 10 million boxes of Cheerios cereal. Five years later, it was discovered that the so-called “Cheerios” Dollars were actually from a different reverse die type.

Some experts consider these pattern coins; others have called them “Reverse of 1999”. PCGS has labeled them “Cheerios FS-401”, referring to the source and the reference number from the Fivaz-Stanton “Cherrypicker” guide.

Because of the perceived rarity of the Reverse of 1999 and the assumption that all “Cheerios” Dollars bore the Reverse of 1999, the demand for these coins has increased and the coins themselves have become quite valuable.

However, PCGS experts recently opened a sealed “Cheerios” package only to find out that the Dollar contained in the package was of a normal, Reverse of 2000 die type.

The package appeared to be authentic and showed no evidence of tampering. A similar experience has been reported by another grading service. Thus, one may no longer assume that the Dollars in the Cheerios packages are of the rare, Reverse of 1999.

Because the “Cheerios” Dollars are packaged obverse up, the reverse cannot be seen. An obverse die marker has been identified on some “Cheerios” Dollars and may assist in identifying Reverse of 1999 Dollars in sealed packages. The die marker consists of die polish extending into the field from Sacagawea’s wrap immediately below and to the left of the mintmark. Whether this die marker is diagnostic of the Reverse of 1999 Sacagawea Dollars remains to be seen. (more…)

Die Variety News #13 Now Available

Die Variety News by Billy CrawfordThe latest May/Jun 2008 issue of Die Variety News online bi-monthly magazine is now available in Adobe Acrobat© rich-text PDF (Portable Document File) which allows the viewer an extremely clear high resolution with dynamic zoom capability and detailed printing of each page.

This May/Jun Issue #13 of DVN Magazine includes highlights on a “2004-D Roosevelt Dime Analysis,” “1988 1c Transitional Varieties,” “Wyoming State Quarter DDRs,” “OIV Doubled Dies Continue,” “Strange Reverse on 2006 Lincoln Cent,” and we continue with more “Presidential Varieties & Heavy Abrading.” Plus our extremely popular “This & That” section, “World Varieties,” “Mint Error Showcase” and our “Variety Spotlight” covers the 1943-S 1c DDO.

Susan Headley , the About.com Coin Guide reviewed this issue in her latest column as follows:

” The cover story for this issue is the mysterious 2004-D Roosevelt Dime which has an apparent doubled ear. The doubled ear is difficult to see in the small photo I have here, but if you click through to Billy’s site and look at the full-sized Die Variety News #13 cover, you’ll see an enlargement of this intriguing coin.

Inside issue #13, Billy examines this remarkable coin and provides an answer to the question people have been asking ever since the coin was discovered: Is it a doubled die? Was this semi-circular mark on the ear made by the same person who added the “extra leaf” to certain Wisconsin Quarters (also done at the Denver Mint in 2004?) Or is this mark just some kind of random die damage? Billy shows us what he thinks is the cause, using his lovely large-sized microphotographs and a clear, point-by-point explanation of his theory.

Mint Error News #23 is Published

Mint Error News magazine #23 by Mike ByersI have to absolutely frank with you and say that I am stunned that this magazine is free! Mike Byers has published yet another amazing issue of his wildly popular Mint Error News Magazine, devoted to error and variety coins. The current issue, number 23 in the series, has more 200 pages cram-packed with information, photos, and price lists relating to error coins! Even the advertisements are fascinating!

Although all of the magazine is interesting and informative, the error coin price guides painstakingly compiled by Al Levy are the only frequently-updated price guides of this type that can be found anywhere on the Web. Levy scans eBay, the widest-reaching coin market in the world, for the closing prices of hundreds of different types, dates, and combinations of errors. For example, on the page containing prices for the “Speared Bison” Nickels and “Extra Leaf” Wisconsin Quarters, we learn that prices are way down, partly due to new material coming on the market. Levy warns us about the do-it-yourself coin-wrapping equipment that allows people to wrap and crimp their own rolls of coins, so one should be very wary bidding on supposedly unsearched rolls that show an error coin on the end.

The cover story is about a Proof Utah State Quarter which was struck on an elliptical clip. (An elliptical clip is a coin blank that was erroneously punched into an oval, rather than round, shape. Such blanks are extremely rare, but for a Proof coin to have such a blank, with all of the careful handling and multiple inspections that Proof coins go through at the Mint, it’s downright newsworthy!)

Experts Say 2000-P Cent Not Doubled Die

By Ken Potter for Numismaster

Overlay or MAD Clash - Overlay created courtesy of B.J. NeffIn my Feb. 19 Numismatic News front page story I revealed that an “Extra Beard” variety had been found by reader James P. McCarthy of Wisconsin. I also noted that I and a number of other variety coins specialists had designated it as a doubled die from a tilted hub.

Now I must report that all the researchers (including yours truly) who attributed it as a doubled die just weeks ago, have unanimously reversed our opinions and have reattributed it as a clashed die from a Misaligned Die (or what is often referred to as a MAD Clash). Those of us who originally suggested that the coin was a doubled die based our opinions on the fact that overlays seemed to neatly fit the area of the so-called extra beard in another area of the beard just perfectly.

However, soon after the variety was first publicized, folks started finding more examples with the so-called extra beards from other dies with obvious clash marks. A closer look at examples struck from the same dies as the original find also showed traces of clash but they were minor and overlooked as trivial by most the first time around. With more “extra beards” being found from other dies with obvious clash marks, a clash had to be reconsidered as a possible cause.

Double Struck Madison Dollar Discovered

Double Struck Madison DollarJeff Makkos of Ohio reports finding a double struck 2007-P James Madison dollar in a Mint-issue set. The type of double strike involved is what errorists refer to as an “In-Collar Double Strike with Rotation Between Strikes.”

The cause may be due to two different scenarios.

The first possibility is that the coin was struck normally and then reentered the coining area falling back over the collar where it was forced back into the collar by a second strike in a position rotated just a few degrees away from the original strike.

Another possibility suggested by CONECA president Mike Diamond, is that coin remained in the collar while the inner sleeve of the collar broke loose and rotated within resulting in the same effect.

Because a coin normally expands in diameter ever so slightly upon ejection it is difficult for it to completely reenter the collar unless forced. The forcing of the coin into the collar often results in it only being forced part way and and edge that looks to have two levels or what is known as a “Partial Collar.” Makkos’ coin does not show a partial collar, indicating that it was either forced all the way back into the collar during the second strike or could have been in a rotating collar.

The Faceless Monroe Presidential Dollar

The Faceless Monroe Dollar is a Monroe Dollar blank that didn't get the front and back coin designs, but did get the edge lettering.Blank Monroe Dollar has Edge Lettering

A “Faceless” Monroe Presidential Dollar has been found by coin collector Garrett Reich of Michigan. This extremely rare error type, of which only one previous specimen has ever been confirmed, is a Presidential Dollar that didn’t get struck by the coin dies, leaving it without any obverse or reverse designs. Reich’s coin is a blank planchet with a very important difference from nearly other blank Presidential Dollar coins: it has Presidential Dollar edge lettering on it! Garrett found the coin in a bank box of 1,000 coins wrapped up into 40 rolls on February 13, 2008, the day before the coins officially went on sale at most banks. (Some banks are known to distribute the coins ahead of the official release date.)

Monroe Faceless Dollar is NGC Certified

Reich’s Faceless Monroe Dollar specimen has been certified by NGC as genuine, with the label reading “2008P (James Monroe) $1 / Edge Lettered Planchet / Mint Error” along with the verification number on the insert. According to Reich’s wife, Erika, the grading service messed up the label the first time around, apparently not recognizing that the particular president was a certain, known fact in this case.

Second Doubled Die Uncovered By Reader

1982 Lincoln Cent Double Die ReverseAfter nearly four months of readers searching, a second example of a major 1982 doubled die reverse cent has finally been uncovered. Numismatic News reader Jim Proctor of Vermont reported it. It bears the small date obverse and is struck on a pure copper-plated zinc core planchet – as was the original find.

Author Charles D. Daughtrey first revealed the existence of the variety to NN readers in a front-page story in the Oct. 2, 2007, issue, crediting Richard J. Ziegler of Massachussettes for the discovery. It represents the second strongest doubled die reverse known on the Lincoln Memorial cent, second only to the major 1983 doubled die cent.

Proctor said that he first became aware of the variety when he saw the NN story in late September 2007. A few weeks later, in late October, he decided to locate some rolls of 1982 small date zinc cents that he had put away back in the early 1980s. They represented coins grading anywhere from almost uncirculated to brilliant uncirculated that he had pulled from circulation on a daily basis and saved in rolls. Read Full Story

The Extra Beard Penny Error

Lincoln Cent ErrorThe 2000-P “Extra Beard” Lincoln Cent doubled die variety shows hub doubling on Lincoln’s neck, along the left side of the beard. According to variety coin expert Ken Potter, who first reported the Extra Beard variety in Numismatic News, the doubling was probably the result of a misalignment of the die during the hubbing process at the Mint.

The doubling appears near the center of the coin, consistent with other doubled die varieties that have been found since the Mint began using the single-step hubbing process. What makes this coin different is that the doubling is offset, or turned to the side, which means that the Mint worker who did the hubbing may have first placed the die into the machine rotated a little bit.

When the kiss of the metal occurred, an impression of the small “extra beard” area was made before the die seated to true. Since the Mint releases very little information about its processes, a fair bit of this is educated speculation, but the explanation seems to make sense. Read Full Story

Major Monroe Dollar Error Coins Confirmed!

Monroe Error CoinCoin World is reporting that the U.S. Mint has accidentally struck between 70,000 and 140,000 Monroe Presidential Dollars on planchets (coin blanks) intended for Statehood Quarters! The error coins were detected and intercepted by the contractor (CoinWrap Inc.,) that wraps the Presidential Dollars for the U.S. Mint. During the coin-wrapping process, CoinWrap workers discovered some “irregular” dollars among Monroe coins struck at the Philadelphia Mint facility. Of course, the contractor immediately Did The Right Thing and gathered all of the misstruck coins and returned them to the U.S. Mint, which will (presumably) destroy them.

The Monroe Presidential Dollar isn’t due to hit circulation until February 14, but banks have been able to order the coins from the Fed since the beginning of February. It will be interesting to see how many of these amazing “wrong planchet errors” actually surface, and in what parts of the country they are found. Read Full Article

List Grows of Proof Spiked Head Error Nickels to Dollars

Proof Spiked Head Kennedy halfBy Ken Potter – I reported upon a Spiked Head die crack on a proof 2007-S Thomas Jefferson Presidential dollar in the Nov. 13, 2007, issue of Numismatic News. What I did not say was that it was actually just one of several Spiked Heads found on proof coins submitted to me in the past year and a half.

New to the list of significant die cracks on proof coins are 12 examples dated 1998-S, 1999-S, 2000-S, 2005-S and 2006-S, spanning all denominations from nickels through a single Sacagawea dollar. The “list” was originally started with a Spiked Head 2002-S silver Kennedy half dollar that headlined the April 15, 2003, issue of NN. This coin prompted a long string of finds that followed as folks began to check other denominations and dates closer.

The 10-part series of reports ran intermittently with the last appearing in the June 14, 2005, issue up until my recent Jefferson dollar story. Read Full Article

Collector Waits Years to Learn Error’s Story

1954-S Roosevelt dime that was double struck in-collarAfter 47 years of ownership, Edgar Murphy of South Carolina decided finally to find out exactly what kind of error he’d purchased as a youth back in 1960. He contacted me by e-mail and made arrangements to send his error coin in for examination.

It turned out to be a rather neat 1954-S Roosevelt dime that was double struck in-collar with the second strike flipped over, what is referred to simply as a “Double Struck Flip Over” in error collector parlance.

Portions of the reverse show through the obverse design and the portions obverse show through the reverse design. The effect is a composite of both designs with the second strike dominating.

An interesting diagnostic of in-collar double strikes is that more than 99 percent of them fail to be forced all the way back down into the collar for the second strike. This is due to very slight expansion of the coin after it is ejected from the collar; after ejection it is too large to fit back in to the collar and needs to be forced in by the strike.

Wyoming Error Found in Quarter Proof Set

Wyoming State Quarter Proof ErrorPaul Kmiotek of New York was in for a big surprise when he opened the 2007 state quarter proof set his in-laws gave him on his birthday. The last thing he expected to find was a major minting error.

When he slid the set out of the box, he saw that the lower right corner of the case was jammed partially open by the high flange of a misstruck 2007-S Wyoming state quarter.

At first he didn’t notice the error and tried to snap the case back closed, but the high flange that was cupped upward from obverse forced it to spring back open. He then noticed the “problem” and decided to contact Numismatic News about his find. The report was forwarded to me and I then consulted with a pool of experts to see what they thought.

Fred Weinberg of Encino, Calif., said, “I’d call it a Close Overlapped Double Strike, Cupped, with a Tilted Partial Collar. As a proof states quarter, I’d estimate it at $1,500-$1,800 retail value.” Read Full Story

PCGS Confirms Lettered-Edge Sac and Plain-Edge Jefferson Dollars

(Newport Beach, California) – Professional Coin Grading Service has certified the first reported Sacagawea golden dollar coin struck with the edge lettering intended only for Presidential dollars. The submitter will receive a $10,000 finder’s reward from PCGS.

“The United States Mint set up specific internal procedures in an attempt to prevent this type of error from happening. But it did happen, and it’s an amazing-looking error,” said Ron Guth, PCGS President.

The 2007-dated coin was struck at the Denver Mint and has been examined and authenticated by the experts at PCGS. The coin was submitted by Andrew Moores of Lakewood, Colorado who found the coin in his pocket change. Moores believes he could have had the coin for as long as two weeks and only noticed it when he compared it with other Sacagawea Dollars that he had already set aside.

Moores was unaware of the reward until a coin collector friend mentioned that he had seen the offer on the PCGS Message Boards. According to Guth, who spoke with the submitter about the find, “Needless to say, Mr. Moores is a very happy man.”

PCGS also confirms it now has certified 301 Jefferson dollars erroneously struck without edge lettering. (more…)

Presidential $1 Error Coins: 2007 Proofs

Proof 2007-S John Adams $1 struck from horizontally misaligned diesAs a general rule, modern proof error coins are scarce. There are several reasons for this. The requirements of special production hinder the number and types of errors that can occur. For one, during production of proof coinage, dies are frequently replaced and, therefore, many of the errors associated with late-state die failure seldom occur. Also, proof coins are placed into special packaging which means that any aberrantly shaped error coin will likely be discovered at the packaging stage. And last, the Mint employs an exceptionally high level of quality control surrounding the production of proof coinage.

NGC did, however, receive a Proof Presidential $1 error coin almost as soon as we began receiving submissions. Surprisingly, this was a relatively dramatic and scare type of error, a coin struck from nonparallel dies also called horizontally misaligned dies. This type of error occurs when the dies are not level with each other during striking. The result is a “wedge-shaped” coin. The misalignment also creates a gap between the collar and the dies. During striking, metal will flow into that gap forming an enlarged and distorted, raised rim or flange. A handful of similar errors of this type have been seen by NGC. Read Full Story

First major die crack on proof Jefferson $1

By Ken Potter on Numismatic News

Proof Jefferson Dollar Die CrackA Spiked Head die crack on a proof 2007-S Thomas Jefferson Presidential dollar has been reported by a San Francisco Bay area collector. It was found in a four-piece 2007 Presidential dollar proof set. The coin exhibits a significant die crack on the reverse running from the second ray from the right in Miss Liberty’s crown up into the field, through the “E” of AMERICA continuing on through the rim. It is the first significant die crack reported on a proof Presidential dollar that runs from a portion of the design all the way through the rim.

The piece also represents the very first major die crack reported on any proof coin dated 2007. The owner (who wishes to remain anonymous) said that he ordered several sets directly from the Mint on June 21 and received them on July 5. Read Full Story

Mules discovered among RCM 2007 Mint sets

RCM 2007 Mint SetA couple of sharp-eyed collectors have discovered a mule error in the Royal Canadian Mint’s 2007 sets.

The error coin couples the wheelchair curling 25-cent piece reverse with the Queen Elizabeth II obverse sporting the Olympic logo. The wheelchair curling coins are supposed to have the Paralympic logo on the obverse.

Both Leo Wagenaar of B.C., and Kevin Mosher of Quebec, purchased their Special Edition Uncirculated Coin Sets directly from the Mint. The sets contain the circulating 1-, 5-, 10- and 50-cent coins, the loonie and toonie, plus the five Olympic 25-cent coins for 2007 (hockey, wheelchair curling, biathlon, curling and downhill skiing).

After his discovery in early August, Wagenaar, who was the first to contact CCN about the error, went on a hunt for more errors, combing post offices and coin shops in Vancouver’s lower mainland area. After searching for several weeks, and ordering more sets from the Mint, he had found seven sets containing the mule, among about 300 he looked at. Read Full Article

25-cent Alpine Skiing Coin Error Reported

OTTAWA, Oct. 26 /CNW Telbec/ – The Royal Canadian Mint confirms that a small number of 25-cent alpine skiing coins produced for collector products issued on October 24, 2007 bear a 2008 date on the obverse, or “heads” side of the coin, rather than the 2007 date. This error is limited to alpine skiing coin sports cards sold exclusively at participating Petro-Canada outlets and a small quantity of Vancouver 2010 Olympic Winter Games coin collections. The 22 million 25-cent alpine skiing coins produced for circulation are not affected.

The Mint is currently investigating the source of this error and will implement the appropriate measures to ensure it does not occur in the future. (more…)

PCGS Certifies 1969-S Doubled Die Cent

1969-S Double Die Lincoln Cent PCGS 64 RedYes, you can still find valuable coins. Professional Coin Grading Service has certified a recently discovered modern rarity, a 1969 San Francisco Mint doubled die obverse Lincoln Cent. It’s graded PCGS Mint State 64 Red and tied for the finest known!

The coin was discovered by Michigan collector, Michael Tremonti, who was examining two rolls of uncirculated 1969-S cents on October 3. After consulting with well-known error-variety expert, Ken Potter, Tremonti submitted the coin to PCGS.

“I was totally amazed that this coin could turn up out of nowhere. The coin is completely original and full mint red. It’s a beautiful near-Gem example,” said David Hall, PCGS co-founder and president of Collectors Universe, Inc. (NASDAQ: CLCT). “What an incredible find! This could be a six-figure coin.”

Legend of 1969-S Double Die Lincoln Cent Including this latest discovery piece, the PCGS Population Report indicates only 23 1969-S doubled die cents from Very Fine to MS-64, and only two are graded Mint State Red.

The coin discovered by Tremonti has strong doubling on the obverse in the date, 1969, and the words, LIBERTY and IN GOD WE TRUST. It’s described by Potter as “a Class I Rotated Hub with counter-clockwise doubling.”

A1969-S doubled die cent, graded PCGS MS-64 Red Brown was sold for $85,100 in the Bowers and Merena Auctions sale in August. The Tremonti coin is full red, tied for finest known with one other MS-64 Red, and with no higher grade examples in the PCGS Population Report. (more…)

PCGC Confirms Clipped Planchet Jefferson $1 Errors

Clipped Planchet Jefferson Error(Newport Beach, California) – Would a damaged dollar be worth only 96.5 cents if 3.5 percent of it is missing? When it’s a clipped planchet error it’s worth more than a buck.

Professional Coin Grading Service has certified two of the recently-released 2007-D Thomas Jefferson dollar coins with nearly identically-located 3.5 percent, semi-circular planchet clips.

“Both coins were discovered in a government-sealed ‘first day of issue’ box as part of a bulk submission sent in by someone who wants to remain anonymous. The graders were surprised to find not one, but two Jefferson dollars with curved planchet clips along the top left edge of the coins when viewed from Jefferson’s portrait,” said Ron Guth, PCGS President.

One coin was graded PCGS MS-66, the other was MS-67.

A clipped planchet, also known as an incomplete planchet error, occurs during the minting process when the coin blank (planchet) is not correctly punched out from a strip of metal. The clip can be curved or straight depending on where it occurred on the strip. In some cases, a planchet clip also can be caused when a struck coin is not properly ejected from the coining press.

From the Grading Room: $50 Gold Eagle Error

$50 Gold Eagle Error NGCThe U. S. Mint’s American Eagle gold bullion coin program debuted in 1986, and this called for the creation of several new collar sizes for the four-piece line-up. There was bound to be some trial and error as a result, yet the number of mint error coins actually escaping careful inspection at the mints has remained extremely small for the American Eagle series.

This amazing gold one-ounce coin dated MCMLXXXVI (1986) is just such an error, a coin struck almost entirely out of the collar. In fact, just a trace of the collar’s reeding is visible along the reverse rim. Both sides reveal tripled images of all peripheral elements, as a consequence of the coin’s unrestrained expansion between strikes.

Coinland.com Reports No Millionaires from Two-Headed Quarters in 2006

Melville, New York (PRWEB) October 1, 2007 — Established in 1999, Coinland.com (http://www.coinland.com), located in New York, is a pioneer in the coin collecting business. The company announced today that after assessing values of two-headed quarters they have not found any resulting millionaires.

Individuals find these two-headed quarters in circulation and hope that they’ve found some extremely rare government mint error. They then have a company like Coinland.com assess the true value of the two-headed quarter only to learn that their coin is not genuine and is worth very little, usually between $5 to $15, depending on how well it’s made and what the face value of the coin is.

Two-headed quarters found in circulation or purchased at swap meets are not made by the U.S. Mint. Rather they have been created as a novelty device, used in magician’s tricks or for pranks. (more…)

Plain Edge Jeff

By Ken Potter on Numismaster

Bruce Countryman of Iowa has reported what appears to be the first confirmed “plain edge” Thomas Jefferson Presidential dollar found. The coin is without the edge inscription, or what is commonly referred to in the hobby as a “plain edge” or “smooth edge” error.

After tens of thousands of the plain edge errors were found on Philadelphia and Denver Mint examples of the George Washington dollars (officially released on Feb. 14), and a much smaller but significant number were found on the Philadelphia John Adams dollars, (officially released on May 17), hobby observers predicted that the same error would repeat itself on the Jefferson dollar. However, weeks went by after their official release on Aug. 16 before one was actually found.

Answers sought for unusual split printing

In the years since 1991, when the Bureau of Engraving and Printing’s Western Currency Facility began operating in Fort Worth, Texas, collectors of current Federal Reserve Notes have grown accustomed to checking for the facility’s “FW” mark on their paper money. Many collectors now seek examples of both Washington, D.C., and Fort Worth notes from each district or block when available.

Some go even further and try to collect all the serial groups formed when production shifted between the two facilities more than once within a single block.

’07-P Jefferson Dollar Doubled Die Reverse

By Ken Potter for Numismaster

Jefferson Dollar errorOn Aug. 16, the day the new Thomas Jefferson Presidential dollars were released to the public, Chuck Chichinski of Bellefontaine, Ohio, went to his bank and obtained two rolls of the coins. Having read a report on the www.coins.about.com Web site that a doubled die reverse existed on the Adams dollar, he quickly went to work to see if any of the new Jeffersons he had obtained had a similar affliction. By the third or fourth coin in his first roll, he discovered that he had found his first Jefferson dollar doubled die reverse!

He called me to report his find on the same day and mailed two of the coins the next day for an attribution. I found that it was not only a doubled die that was similar to the Adams doubled die reverse that Chichinski had seen on the Internet on researcher Billy Crawford’s Web site but that it was almost identical to an earlier find that was reported by John Wexler recently. The only difference was that this one was even more prominent than any of the earlier listings.

Washington Doubled Die or Just a Coincidence?

This Abraded Patch on Washington Dollar Intrigues Expert

Well-known die variety expert Billy Crawford sent me these enigmatic photos. There is a patch of surface area in the field of this Washington Presidential Dollar reverse that has been abraded by a Mint technician. Mint workers abrade the coin dies when they need to clean up problems such as clash marks or other damage to the face of the dies. After the abrading, which obscures the fault, the die should be polished to bring the surface back to a smooth texture. The first photo shows a wide angle view of the area we are examining here.

Gnarled Edges, Out-Of-Round Strikes Found On Adams Dollars

By Ken Potter

Several Numismatic News readers have alerted us of Presidential dollars that are afflicted by what I call gnarled rims. I’ve had reports on these ever since the George Washington dollar was released on through to the latest Thomas Jefferson dollars. The ones we show here are two of the Philadelphia Mint John Adams dollars sent in by a reader. In each case we see that the gnarled rims are on one side or the other but not on both. We also see that the high points of the gnarling goes hand in hand with edge characters that are heavily punched into the rim of the coin shifted to one side or the other. In effect the letters are shifted so close to one side of the rim that they are causing metal displacement to be evidenced on the rim they are bordering. The information on the submitter of this coin has been misplaced and I’d like for that person to contact me so that credits can be extended.
