Collectible coins encompass a wide range of types, including patterns, trial coins, and various other categories. Patterns are coins struck to test the design and production methods before mass production, often featuring distinctive elements that may differ from standard issues. Trial coins, especially those from the 1870s, such as the trial pieces produced by the U.S. Mint, were typically created to assess new designs or manufacturing techniques. Collectors often seek these coins for their historical significance and rarity, making them valuable additions to numismatic collections, particularly those focused on American coinage.
