Patterns are experimental coins created to test new designs, compositions, or minting techniques before official production. In the United States, coins classified as patterns typically include those produced for the purpose of evaluating their acceptability. The 1880 patterns, specifically, refer to a series of test pieces created during that year, which featured various designs including potential changes to existing currency. These coins are highly sought after by collectors due to their rarity and historical significance in U.S. numismatics.
