Collectible coins, particularly those from the United States, encompass a wide variety of categories, including patterns and trial coins. Patterns are experimental coins struck to test designs or composition before a final version is approved for circulation. Trial coins from 1853 specifically relate to the U.S. Mint's efforts to refine the design and production process for new denominations, particularly in response to changes in the economy and public demand. These items are often sought after by numismatists for their historical significance and rarity.
