Collectible coins encompass a variety of types, including patterns and trial coins. Patterns are experimental pieces made to test new designs or technologies before official minting. Trial coins, such as those from 1863, were struck to assess design and production methods, often in limited quantities and not intended for circulation. In the United States, these coins hold significant historical and numismatic value due to their rarity and the insight they provide into the minting processes of the era.
