Coins are an important category of collectible items, particularly in numismatics, where enthusiasts focus on extracting historical, cultural, and aesthetic value. One notable type of collectible coin includes patterns, which are experimental issues created to test designs or manufacturing processes prior to mass production. In the United States, a significant year for pattern coins was 1863, as various designs were produced that showcased innovative features but were not intended for circulation. These coins are highly sought after by collectors due to their rarity, historical significance, and the insight they provide into the coinage process of their era.
