Collar
A metal piece that either positions a planchet beneath the dies and/or restrains the expanding metal of a coin during striking. Collars are considered the third die and, today, are used to impart the edge markings to a coin. Collars can be merely a hole in a flat piece of metal or a set of segments that pull away from the coin after it is struck.
