The only currently known 1942 Lincoln cent pattern struck in aluminum, with a plain edge, is one of the 483 lots to be offered during Heritage Auctions’ April 24 Platinum Night in Schaumburg, Ill.
The cent is graded Proof 66 by Professional Coin Grading Service.
The pattern cents of 1942 are split into two groups — those modeled after the Colombian 2-centavo coin, and those bearing the regular Lincoln cent designs.
While the 10th edition of United States Pattern Coins, Experimental & Trial Pieces by J. Hewitt Judd, edited by Q. David Bowers, suggests additional metallic compositions for the 1942 cent patterns may have been struck with the regular issue dies, currently known examples are only those struck in aluminum, zinc-coated steel and white metal.
The Heritage auction, including Platinum Night, will be offered April 23 to 26 in conjunction with the Central States Numismatic Society 75th Anniversary Convention at the Renaissance Schaumburg Convention Center.
Unique in aluminum
PCGS had the unique Judd 2079 1942 pattern cent metallurgically analyzed several years ago after it was pulled from a Heritage March 2008 sale where auction materials originally described it as being white metal. The pattern cent was withdrawn in response to questions raised about the composition. The coin was resubmitted to PCGS for the analysis.
The analysis determined the alloy to be 98 percent aluminum, 0.7 percent silicon, 0.6 percent iron, 0.5 percent silver and 0.4 percent magnesium.
The pattern cent’s weight is 1.563 grams, approximately half the normal 3.11 grams for a regular issue 1942 Lincoln cent.
The 1942 Lincoln aluminum cent pattern was offered again by Heritage in a May 29, 2009, Long Beach Auction session, where it realized $126,500.
