Collectible coins encompass various types, including patterns, which are experimental or trial pieces created to test new designs or manufacturing processes. The 1869 Philadelphia pattern coins were produced in small quantities, often using different metals and designs than standard circulating coins of the era. These pieces are of particular interest to collectors due to their rarity and historical significance in the context of U.S. numismatics. The United States Mint in Philadelphia was instrumental in producing these patterns, making them an important aspect of American coinage history.
