Collectible coins encompass a variety of types, including historical, commemorative, and bullion coins. The American Liberty Gold coin is a notable collectible, often associated with the Twenty Dollar gold pieces minted in the early 20th century. Coins from the year 1863, particularly those struck in San Francisco, hold additional historical significance due to their rarity and the historical context of the Civil War era in the United States. Collectors often seek these coins for their artistic design, metallic content, and as investment pieces.
