Collectible coins encompass various types, including patterns, trial coins, and denominations issued by the United States of America. Patterns are experimental designs created to test new coinage concepts, often unique and historically significant. Trial coins, such as those from 1858, were minted to assess new designs or technologies before broader production. The status of many collectible coins, particularly unique or rare pieces, may remain unknown due to limited documentation or their scarcity in the marketplace.
