Collectible coins encompass a wide range of types, including historical pieces, patterns, and trial coins. The United States One Cent Penny, particularly from 1860, is notable for its role in American numismatics. Patterns are experimental coins created to test designs and compositions before official minting, while trial coins are produced to assess the feasibility of new coinage ideas. These items can be highly sought after by collectors due to their rarity and unique historical significance.
