Collectible coins encompass a wide range of types, including patterns and trial coins. Trial coins, such as those produced in 1867 in Philadelphia, were experimental pieces created to test new designs or minting techniques before full-scale production. These coins often hold significant value among collectors due to their historical relevance and limited availability, representing important milestones in the numismatic history of the United States.
