Patterns are specially minted coins created to test new designs or compositions prior to mass production. The Fifty Cents coin from 1861, struck in Philadelphia, is a notable example of a trial coin. These pieces often showcase unique design features that may differ from the final issued coins. Collectors highly value such patterns due to their rarity and historical significance in numismatics.
