Collectible coins, particularly in the context of the United States, encompass a wide range of categories, including denominations like the Two and a Half Dollar. The 1874 trial coins, also known as patterns, were minted in Philadelphia and represent experimental designs or compositions that were not intended for general circulation. These coins are highly sought after by collectors due to their rarity and historical significance, often reflecting the evolution of U.S. coinage during the 19th century.
