Collectible coins, particularly in the context of the United States, encompass a variety of categories that appeal to numismatists. Among these are the Two and a Half Dollar coins, also known as Quarter Eagles, minted from 1796 to 1929, featuring iconic designs like the Liberty Head and Indian Head. Notably, trial coins and patterns, including those from 1861, were created as experimental pieces to test designs, compositions, or minting processes before full-scale production. These coins often hold significant historical value and are highly sought after by collectors for their rarity and uniqueness.
