The 1871 Trial Coins, particularly the One Cent Penny, are a notable type of collectible coin within U.S. numismatics. These coins were produced as experimental pieces to test new designs and minting processes. Patterns such as the 1871 penny were often not released for circulation and are prized by collectors for their historical significance and limited availability. The 1871 Trial Coins exemplify the innovation in American coinage during that era.
