Collectible coins are a specialized category of numismatics that includes various types, such as patterns and trial coins. Patterns are prototypes or experimental designs produced before a new coin is officially minted, often in limited numbers, making them highly sought after by collectors. Trial coins, similar in purpose, were created to test die designs and techniques; they can feature different metals or designs than those ultimately adopted for circulation. The year 1881 is notable for several collectible coins in the United States, including specific patterns that reflect the era's minting practices and artistic trends.
