What's So Special About the 1943 Copper Penny?
According to the American Numismatic Association, the 1943 copper-alloy cent is one of the most idealized and potentially one of the most sought-after items in American numismatics. Nearly all circulating pennies in that year were struck in zinc-coated steel because copper and nickel were needed for the Allied war effort.
Forty 1943 copper-alloy cents are known to remain in existence. Coin experts speculate that they were struck by accident because copper-alloy blanks, left in the press from the year before, were struck when production began on the new steel pennies.
A 1943 copper cent was first offered for sale in 1958, bringing more than $40,000. A subsequent piece sold for $10,000 at an ANA convention in 1981. The highest amount paid for a 1943 copper cent was $82,500 in 1996.
Because of its collector value, the 1943 copper cent has been counterfeited by coating steel cents with copper or by altering the dates of 1945, 1948, and 1949 pennies.
But you can tell if a 1943 cent is made of steel rather than copper by using a magnet. If the coin is attracted to the magnet, it is not copper. If it does not stick, the coin might be of copper and should be authenticated by an expert.
