From the Grading Room: 1973-S Dollar on a Copper-Nickel Planchet
Coins struck accidentally on planchets intended for other issues are known for quite a number of United States coin types, but they are rarely more spectacular than when occurring with dollar coins. This superb gem Eisenhower Dollar was struck at the San Francisco Mint for inclusion in the series of “blue pack” silver-clad dollars offered by the U. S. Mint at $3 apiece from 1971 to 1974.
At first glance it could almost pass for one of these silver-clad pieces, but inspection of its edge (made all the more easy through NGC’s unique EdgeView® holder) reveals the bright orange-red glow of a copper-nickel-clad planchet! This coin has the satiny texture typical of most silver-clad dollars and confirms that it was struck accidentally as part of that series.
The Denver Mint was assigned the role of preparing planchets for San Francisco’s production of the “blue” Ikes, but it was simultaneously making planchets of the copper-nickel-clad composition for its own press run of circulating coins. One of these ordinary planchets evidently found its way into a shipment of silver-clad planchets going to San Francisco and was struck and packaged as a silver-clad issue. While this scenario describes how such an error could have occurred, it did not play out very often. This is the first report of a 1973-S Dollar struck on a copper-nickel planchet.
If that weren’t enough to excite collectors, this coin is also a doubled-die obverse variety! It is DDO-2 as listed and illustrated in the book CONECA Attribution Guide to Eisenhower Dollar Die Varieties by James Wiles, Ph.D. This variety, previously known only in the normal silver-clad composition, is now confirmed on a copper-nickel-clad planchet intended for currency strikes. Collectors should check their “blue packs” for more new discoveries.

One of only two known 1944-San Francisco Steel Cents was auctioned on July 31 in 
From July 30 to Aug. 3, thousands of coin collectors flocked to Baltimore to attend the annual Summer ANA Convention. Among the most newsworthy of events at the Convention were the sales of two San Francisco Mint pennies. On July 30, a 1943-S copper cent sold on the bourse floor and, on July 31, a 1944-S steel cent sold at auction. The topic here is the copper cents of 1943, with emphasis upon this specific 1943-S copper cent. In part 2, steel cents of 1944 will be discussed, with the focus being upon the 1944-S that set an astounding record, along with additional reasons as to why 1943 coppers and 1944 steel cents are interesting and important.
Steel cents of 1943 have sort of a silvery-white look. It is readily apparent that these are not composed of copper. For unknown reasons, however, a few 1943 cents were minted in copper, and are extremely rare. It is generally believed that a few leftover copper planchets (prepared blanks) were stuck, for a while, in the mechanism that channeled the planchets to the coinage presses. As these copper planchets became unstuck eventually, due to the movements within the mechanisms, and joined the flow, they were struck into coins. Conversely, in 1944, a few steel cents were minted as a consequence of leftover steel planchets joining the flow of copper planchets.
