A 1943 zinc-coated steel Lincoln penny is worth less than 10 cents today. But a 1943 one-of-a-kind copper alloy Lincoln penny struck at the Denver Mint was recently sold by a New Jersey coin dealer for a record $1.7 million. The anonymous previous owner donated the coin to a charity before the sale so the charity would get the proceeds. The new owner also owns bronze 1943 pennies struck at the Philadelphia and San Francisco mints, and will show all three pennies at a coin show in Tampa in January. (Bronze is a copper alloy—but people always refer to the pennies as "copper.") It is thought that fewer than 20 of the bronze error pennies were made, and the coin that just sold is believed to be the only one minted in Denver. A few fakes have been discovered.
