I’ve discussed many times the process in which how nice coins are assigned price levels. But how are problem coins valued? This is an interesting question and one which is becoming a bit easier to answer since NCS coins have become a well-accepted part of numismatics.

(Before I begin, I should state here that NCS or Numismatic Conservation Services is a division of NGC that certifies and encapsulates “problem coins” which NGC does not see fit to put in their regular holders. This includes coins that are harshly cleaned, polished, heavily scratched, rim filed, etc. NCS only uses adjectival grades—i.e., they would call a coin “AU details” as opposed to “AU55 details.”)

The reason why non-problem coins are easier to value than problem coins is, well, because they don’t have problems. There is a greater degree of consistency of appearance between an 1830 half eagle in PCGS AU55 (or NGC AU55) than there is with this same issue when it has the details of an AU55 but it has been cleaned.

Let me explain what I mean by this. If you were to call me up and offer me an 1830 half eagle in PCGS AU55, I would have a decent idea of what to expect. I’m figuring that it has light wear, a decent amount of remaining luster, maybe a few scattered marks in the fields and probably a pretty good overall appearance. But if you call me an offer me an 1830 half eagle in an NCS holder that states the coin has “AU details” but has been “cleaned,” I’m not sure what to expect. Has it been lightly cleaned or harshly cleaned? Does it have an acceptable appearance or does it look overly shiny from having been polished or perhaps whizzed?

From my experience with viewing NCS coins, there is a very wide range of coins in these holders.

I’ve seen coins that NCS has called “cleaned” that look pretty acceptable to me; not very different, in fact, from coins encapsulated by both NGC and PCGS. I’ve also seen coins placed in NCS holders that had planchet flaws or mint-made surface that, in my opinion, could just as easily be in “normal” NGC or PCGS holders.

But back to cleaned coins and how to value them. As a general rule of thumb, I think that if a coin has been lightly cleaned it is worth around half of what a non-cleaned example would be worth. The NGC or PCGS AU55 1830 half eagle that I mentioned above is a $60,000 coin if it has a decent, original appearance. In an NCS “AU details—cleaned” holder it’s more likely worth $30,000 or so. And if it’s a very harshly cleaned AU coin with some damage as well it is more likely worth in the area of $15,000-20,000. (more…)

Take two 1842-O Liberty Head eagles in NGC AU58. One is worth $11,500 and gets multiple orders on my website within hours of being posted. The other sells in an auction for $6,325 and is a marginal value. Why is one coin worth nearly twice as much as the other despite the fact that they are the same date in the “same” grade?

The coin(s) in question is, as I stated above, an 1842-O eagle in AU58. A little background information on this issue is appropriate to help better understand the issue at hand. A total of 27,400 examples were produced. This issue saw extensive use in commerce and it is essentially the first available eagle from this mint given the rarity of the 1841-O (only 2,500 were produced). When available, the 1842-O tends to be in VF and EF grades and it is scarce in the lower AU grades. It becomes rare in properly graded AU55 and it is very rare in AU58. This issue is an extreme rarity in Mint State with just two or three known. The second finest of these, graded MS61 by PCGS, just brought $74,750 in the August 2010 Stack’s auction.

I bought the NGC AU58 example illustrated below at the recent Philadelphia coin show sponsored by Whitman and it was among my best purchases at the show. I paid a strong price for this coin but was happy to do so (and would do so again).

What makes this a special coin? I was really attracted top this coin by its originality. It has superb deep original coloration on the obverse and reverse which suggests that it has never been cleaned or dipped. Notice the depth of the color and how even it is on both sides. I also like how clean the surfaces are. This is an issue that is typically found with densely abraded surfaces and even the MS61 piece that I mentioned above had considerable marks on the surfaces. This example, however, was immaculate. The luster of this coin, while a bit subdued as a result of the intensity of the color, is undisturbed; a result of its not having been cleaned, dipped or processed. This coin has wonderful overall eye appeal and this sort of “look” is much appreciated by connoisseurs of U.S. gold coins. (more…)

I recently bought and sold a seemingly innocuous 1859-D quarter eagle that had a great degree of numismatic significance. Before I explain why, let me give you a little background on the specific coin and on this issue in general.

This 1859-D quarter eagle has been graded as Fine-15 by PCGS. It is the single lowest graded example of this date seen by either service. In looking back through my records, I have seen very few that grade below Extremely Fine and certainly can’t recall a non-damaged Fine example.

The example I sold is problem-free and actually quite attractive despite its extensive wear. It shows nice natural coloration and the obverse is a full Very Fine from the standpoint of detail.

This is the final quarter eagle produced at the Dahlonega mint. But, for all intents and purposes, the death knell for this denomination at the Dahlonega mint had been spelled as early as 1854 when mintages figures declined precipitously from the 1840’s. In 1856, only 874 were struck; making this the lowest mintage figure of any coin ever produced at this branch mint. In 1857-D, the mintage increased to 2,364 but no quarter eagles were made in 1858. 1859 saw a resumption of the denomination but only to the tune of 2,244 coins. None were struck in 1860 and when the mint closed in 1861, no further plans had been made to coin quarter eagles.

The 1857-D and 1859-D are interesting issues among the quarter eagles from this mint. The grade distribution is different for these issues than for nearly all other coins from Dahlonega. The coins from the 1840’s and early 1850’s have what I regard as a typical distribution of survivors: most are in the VF-EF range with AU coins being scarce to rare and Uncirculated coins being very rare to extremely rare.

But in 1857 and 1859, the distribution curve looks different. These two dates are almost never seen in grades below EF and are most often seen in About Uncirculated. Both are rare in Uncirculated but not as much so as their very low mintage figures would suggest. There are as many as ten Uncirculated 1859-D quarter eagles known as well as another four or five dozen in About Uncirculated. This doesn’t seem like a lot of coins but when you consider that there are only 150 or so known from the original mintage, the fact that nearly half grade AU or better suggests that this issue didn’t circulate as freely as the quarter eagles from the 1840’s.

I had long believed that the 1859-D was an issue that saw very little circulation. The existence of the coin shown above is proof that at least a few examples did circulate. I don’t believe that this Fine-15 example was a pocket piece as it shows all the hallmarks of extensive natural circulation. Ironically, it is more rare in this grade than it is in Uncirculated and, to my way of thinking, this is one of the neater Dahlonega quarter eagles to have come up for sale this year: a highly circulated example of a date that was hitherto believed to have never seen extensive circulation. Considering that this coin cost its new owner well under $2,000 I think it is an amazing piece of Southern gold history.
