Collectible coins, particularly those from the United States, encompass a wide range of categories, including patterns and trial coins. Patterns are typically experimental pieces struck to test designs before they are adopted for regular minting, while trial coins are struck in limited numbers to evaluate various aspects of the production process. The year 1858 is significant as it marks the minting of various trial coins, including designs that played a crucial role in the development of future U.S. coinage. Collectors often seek these pieces for their historical importance and uniqueness, making them valuable in the numismatic market.
