An off center coin is produced when the coin is struck once, albeit off center. Unlike a broadstrike, the punch of an off center coin is not in the center of the coin, but rather the edge. This results in a coin which is not circular.
The coin gives a freakish appearance as a result, and various amounts of blank planchet space are visible. The coins can vary in value because of how far off center they are struck, although coins with full dates are more desirable than coins without a date or missing digits.
An off center coin is one of the most common and best known types of errors. This happens when a blank which is supposed to be fed into the press, lands in the collar improperly. When this occurs only part of the blank is between the upper and lower dies. When the dies strike the blank, only that part will be struck with a design.
