Collectible coins encompass various types, including patterns, which are experimental or trial coins created to test designs before official production. The 1857 P25c, or the quarter dollar pattern, is one such example from the United States, showcasing innovative designs that may not have been adopted for circulation. These coins are highly sought after by collectors due to their rarity and historical significance, often reflecting changes in minting techniques and artistic trends of the era.
