Collectible coins encompass a wide range of types, including ancient coins, modern commemoratives, and bullion coins. In the context of the United States, notable collectible coins include those issued before 1776, which comprise private and regional issues reflecting early American commerce and trade. The year 1860 is significant in numismatic history, marking the pre-Civil War era when coins began to feature more standardized designs and materials, leading to the establishment of a more unified coinage system. Collectors often seek these historical coins for their rarity, historical significance, and aesthetic appeal.
