Doubled Die Errors: These occur when the die used to strike the coins has been misaligned, leading to duplicated details in the design.
This can affect features like the date, motto, or Kennedy’s profile.
Clashed Dies: This error happens when two dies collide without a planchet (coin blank) in between, causing parts of one die's design to be imprinted onto another die.
Off-Center Strikes: An off-center strike occurs when the coin blank isn’t perfectly aligned with the die during the striking process.
Misaligned Reverses: This error happens when the reverse side of the coin is not aligned correctly with the obverse during the striking process.
Planchet Errors: These include issues with the coin blank itself, such as being improperly cut or having imperfections.
Overstruck Errors: This occurs when a coin is struck with a die that has previously been used to strike another coin
Bowed Planchets: A bowed planchet occurs when the coin blank is not perfectly flat, leading to a distortion in the final strike.
