Collectible coins, particularly in the United States, encompass a wide range of items, including patterns, which are trial pieces or concept designs created before official coin production. The 1859 One Dollar pattern, minted in Philadelphia, is a notable example, representing the transitional phase in coin design and production. These coins often attract collectors due to their rarity, historical significance, and unique artistic qualities, making them valuable in the numismatic market.
