The 1874 Ten Dollar Pattern coins are experimental pieces created to test potential designs and compositions for the U.S. mint. These coins, made in small quantities, were not released for circulation, making them highly collectible among numismatists. Patterns often feature unique designs that differ from standard issue coins, and they provide insight into the historical evolution of U.S. coinage. The rarity and limited production of these trial coins contribute to their value in the collectible coin market.
