All the pennies in 1943 year were supposed to be minted as the steel pennies or war pennies. Coin analysts suggest that copper plates may have been tested or left mixed amongst the other steel plates from 1942 and thus the error. No matter what the cause, these coins are selling for just under $100,000 dollars.

Warning: There are many 1943 Copper Penny fakes floating around. You can take a 1948 copper penny and file down the left side of the 8 to make it into a 3.

You also want to watch out for fake 1942 copper pennies that are actually just copper plated 1943 steel pennies. Its not very hard to copper plate a coin and scam artists do it often. CoinTrackers suggests using a magnet to verify the coins content. If it sticks to the magnet, it is a copper plated steel and fake.

Back in 2012, a 1943 Lincoln penny sold for $1 million at auction. That penny was erroneously made of bronze instead of zinc-coated steel at the San Francisco Mint, according to UPI news agency. Texas Rangers co-chairman Bob R. Simpson bought the coin.
