Coin Errors and Misstrikes


A master list of articles we’ve written about error coins, misstrikes, wrongly minted coins and coin press mishaps. Research your own dodgy looking coin and learn if it’s really a genuine coin error or PMD -damage after the coin was minted. Coin errors can be worth tens times their face value or even ten thousand times their face value -if they are real and in good condition. Take a look at our list of coin errors. Happy error collecting!
