Collectible coins encompass a wide range of types, with notable examples including patterns and trial coins. Patterns are experimental designs created by mints to test public response before official release, while trial coins often serve as prototypes for circulation pieces. The year 1864 is significant in U.S. numismatics, as it saw the introduction of the iconic Indian Head cent and notable trial strikes associated with it, reflecting evolving design and production techniques in American coinage. Collectors often seek these items due to their rarity and historical importance.
