Collectible coins, particularly the patterns minted in the United States around 1857, represent significant examples in numismatics. Patterns are trial pieces or experimental coins created to test designs before full-scale production. The 1857 P1c pattern, for instance, features unique characteristics and often has a limited mintage, making it highly sought after by collectors. These coins provide insight into the evolution of American coinage and are prized for their rarity and historical context.
