Collectible coins refer to coins that are sought after by collectors for their historical, artistic, or numismatic value rather than their face value. In the United States, notable examples include the $3 gold piece, minted from 1854 to 1889, and the three-cent nickel, produced between 1865 and 1889. The $3 gold coin represents a unique denomination designed primarily for commerce and is known for its distinctive design, while the nickel three cents was created during the Civil War era to alleviate coin shortages and is notable for its small size and unique composition. Each of these coins has specific features and mintages that contribute to their desirability among collectors.
