Coins, particularly in the context of collectibles, are numismatic items that hold value due to their rarity, historical significance, and demand among collectors. The United States has a rich history of coinage, with various types such as patterns, which are trial strikes made to test new designs or changes before mass production. One noteworthy year for patterns is 1866, when several unique and experimental designs were created as the U.S. transitioned to new coinage systems following the Civil War. Collectors often seek these coins for their unique attributes and the stories they represent within American history.
