Adjustment Strike Error
An adjustment strike error is oddity unto itself. When the U.S. Mint begins coining a new series or sets new dies they must make sure the striking pressure is perfect to strike all the details of the coin. If it’s too much then it can break the die, if it’s not enough then the coin is struck too weak. It’s called die adjustments and they strike planchets until they get the appropriate striking pressure for the coin series.
Die adjustment strike error is also known as die trials. This error occurs when a coin is struck from the press with very little pressure. When the press is being set up and adjusted, extremely weak strikes occur as the strike pressure reaches its optimum level. These die trials are destroyed after being struck and are rarely found in circulation.
