In the truest form, patterncoins illustrate new designs produced by the Mint that are different from those currently being used, or, in some instances, proposals for forthcoming designs intended to replace those currently in use.
Coins struck to test the dies, the coining process, or some other aspect of coinage production are known as trial pieces.
Experimental pieces or coins are those struck to test new concepts, such as different alloys of silver and copper, the feasibility of aluminum for coinage, the use of holes in the center of a coin to enlarge the diameter while retaining the same weight, etc.
