Collectible coins encompass a variety of types, including patterns and trial coins. Patterns are experimental pieces created to test designs before official minting, often exhibiting unique attributes compared to their standard counterparts. Trial coins from the year 1878 are particularly sought after, as they provide insight into the evolution of coinage during a transformative period in U.S. history. These coins can be rare and valuable, attracting interest from numismatists and investors alike.
