Die Caps (also known as Capped Die) occur when a planchet is fed into the coin press. The previous planchet did not eject and the first planchet sticks to one of the coin dies. After repeated strikes, the first planchet starts taking the form of a bottle cap. Place your comments and questions in this forum area about die caps.
Broadstrike Errors happen when a coin is in below the dies in the striking chamber and the collar that holds the coin in place is not engaged properly. Since the metal is softened before striking, the coin press strikes the planchet without the collar in place resulting in unusual shapes. Post your questions and comments in this area that are related to broadstrikes.
Off Center error coins occur when a planchet that is struck by a coin press is not centered under the dies. The amount of off centering will vary. Off center coins that have the date apparent can bring a premium. Please post your questions and comments in this forum that are related to Off Center Error coins.
Double, Triple and Multiple stuck error coins occur when a recently stuck coin is unable to clear the striking chamber. The end result is that the coin may be struck two, three or multiple times. Most of the additional strikes had a good chance of being off center, resulting in a dramatic looking coin.

Double Denomination Errors occur when a coin is properly struck by a coin press. The coin then is inadvertently placed into the hopper of another denomination and also struck by that coin press as well.
