Collectible coins encompass various types, including historical pieces, commemorative issues, and bullion coins. The United States has produced numerous collectible coins, with the twenty-dollar gold coin, known as the Saint-Gaudens Double Eagle, being particularly notable. The American Liberty Gold series, introduced by the U.S. Mint, honors the concept of liberty with intricate designs. Coins minted in 1891, especially those from the Carson City Mint, are sought after by collectors due to their limited production and historical significance.
