Collectible coins encompass a wide range of types, including historical pieces, commemoratives, and errors. In the United States, notable examples include the 1856 Flying Eagle cent, which served as an experimental coin in the transition to modern cents. Trial coins, such as patterns, are specially struck pieces that were created to test designs and compositions prior to mass production. These coins often hold significant historical value and are sought after by collectors for their rarity and unique characteristics.
