The 1943 Copper Lincoln Penny is widely considered the rarest and most valuable error coin ever minted. With only a minuscule number believed to exist, its unique composition makes it an extraordinary numismatic treasure.
The Uniqueness of the 1943 Copper Penny
During World War II, copper was a vital material for the war effort. To conserve resources, the United States Mint transitioned from striking pennies on bronze (an alloy primarily of copper) to zinc-coated steel planchets in 1943. However, due to an astonishing oversight, a very small quantity of pennies were mistakenly struck on the standard bronze planchets that year. This error created one of the most sought-after and elusive coins in U.S. history.
Why it's so rare:
- Material Error: The striking of pennies on copper instead of steel in 1943 was a significant production error, as copper was meant to be entirely phased out for pennies that year.
- Extremely Limited Survival: It is estimated that as few as 15 of these copper pennies exist today, making them extraordinarily rare.
- High Demand: The historical context combined with extreme scarcity drives their immense value among collectors.

Identifying a 1943 Copper Penny
Given its immense value, counterfeit 1943 copper pennies are common. Collectors and enthusiasts should exercise extreme caution and seek professional authentication. Genuine 1943 copper pennies will not stick to a magnet, unlike their steel counterparts. However, many fakes exist, including steel pennies that have been copper-plated or 1948 pennies with the "8" altered to a "3."
If you believe you have found a 1943 copper penny, it is crucial to:
- Perform a Magnet Test: A genuine 1943 copper penny will not be attracted to a magnet. A steel penny, which is far more common, will stick to a magnet.
- Seek Professional Grading: The only definitive way to authenticate and grade such a valuable coin is through reputable third-party grading services like PCGS (Professional Coin Grading Service) or NGC (Numismatic Guaranty Company).
While the 1943 Copper Lincoln Penny holds the top spot for rarity among widely recognized error coins, other significant errors exist, but few match its scarcity and historical significance.
