The value of a penny can skyrocket into the millions due to rare minting errors, low mintage numbers, or their pristine condition. Based on notable sales and extreme rarity, here are 16 ultra-rare penny coins valued by numismatists:
Note on Rarity: Many of these high-value coins are due to minting errors. For example, the 1943 bronze pennies were accidentally struck on leftover bronze planchets when the U.S. Mint was using zinc-coated steel to conserve copper for the war effort. Similarly, the 1944 steel pennies were accidentally struck on leftover steel planchets from 1943. Doubled Die errors, like on the 1955 and 1958 cents, occurred when the die was incorrectly struck twice, causing the date and lettering to appear doubled.
