Collectible coins encompass a variety of types, including patterns, which are trial pieces created to test designs before mass production. In the context of United States coins, the 1870 patterns are particularly notable, as they reflect innovative designs that were never officially minted for circulation. These coins can hold significant historical and monetary value among collectors due to their rarity and the insight they provide into the numismatic practices of that era. The 1870 patterns, including denominations like the dollar and quarter, are highly sought after for their artistry and historical context within American coinage.
