Collectible coins, particularly those issued by the United States, encompass a wide range of types including patterns, which are experimental or prototype coins created to test designs before official minting. The 1906 P 20, commonly referred to as the 20 Dollar gold piece, is notable for its unique design and limited mintage, which makes it highly sought after by collectors. Patterns often feature distinctive modifications or artistic elements not found in standard issue coins, adding to their rarity and appeal in the numismatic community.
