Collectible coins, particularly patterns, are unique or trial pieces created to test designs or minting techniques before official production. In the United States, the 1866 patterns are notable, as they marked a significant year in coin design history, particularly with the introduction of new elements in the coinage. These coins often hold substantial numismatic value due to their rarity and the historical context surrounding their minting.
