N/A - Coins

Collectible coins, such as the United States twenty-dollar gold coin, often include notable varieties like patterns and trial coins. The 1866 twenty-dollar coin is significant due to its design and historical context within U.S. numismatics. Patterns are prototype coins designed to test new designs, while trial coins are struck to evaluate minting processes or designs before mass production. The designation "N A" typically refers to a specific grading or attribution by a numismatic authority. These coins can hold substantial value due to their rarity, historical significance, and the demand among collectors.
