Frequently asked questions
What is a wrong planchet error?
It is a coin struck on a blank intended for a different denomination or metal — for example a cent struck on a dime planchet, or a 1943 cent struck on a leftover copper blank. The wrong weight, size, or color is the giveaway.
How much is an off-metal coin worth?
Values range widely — modest wrong-planchet errors bring a few hundred dollars, while famous transitional and off-metal rarities like the 1943 bronze cent can be worth six or seven figures. Weight and authentication are essential.
