Collectible coins, particularly from the United States, include a variety of types and classifications such as patterns, which are trial strikes created to test designs before official release. The 1861 patterns are noteworthy examples, reflecting a transitional period in American coinage with designs that were never mass-produced. These coins often feature unique variations and are highly sought after by collectors, making them valuable due to their rarity and historical significance within the numismatic community.
