Collectible coins, particularly in the context of United States numismatics, include items such as patterns, which are experimental coins struck to test designs before regular production. The 1880 One Dollar pattern coins represent a fascinating subset of U.S. coinage, showcasing innovative design changes that were considered but not adopted for circulation. These patterns often feature distinct characteristics and are produced in limited quantities, making them highly sought after by collectors and investors due to their rarity and historical significance.
