Incorrect Planchet Mint Error


An incorrect planchet is when a die of a certain type and/or denomination that strikes a planchet not intended for that type and denomination. It can be a nickel struck on a dime planchet or a half dollar struck on a quarter planchet, or any other combination. You can identify an incorrect planchet by weight and by site if the intended design is larger or smaller than the planchet it is struck on.

Incorrect or wrong planchet errors can be worth $400 for a cent struck on a dime planchet to $18,000 for a 1983 Cent struck on a 95% copper planchet (supposed to be copper plated zinc planchet in 1983). Value will depend on rarity, coin type and denomination as well as which planchet alloy the coin is struck on.

1943 Copper Cent Value

Above: 1943 Cent, Struck on a Bronze Planchet, graded AU58 by PCGS.
 
Heritage’s comment on their origin quote: “When the Mint switched from bronze to zinc-plated steel for cent coinage, a handful of leftover bronze planchets nevertheless found their way into the coining press and were stamped with the date 1943. This occurred at all three Mint facilities to strike cents that year, though a majority of the known 1943 bronze or “copper” cents were struck in Philadelphia, not Denver or San Francisco. Fewer than 20 are known.”
 
Collectors should be on the look out for copper plated steel cents and should test all possible 1943 dated copper planchet with a magnet. A copper plated or coated steel cent will attract to a magnet.
