The $20 Liberty Gold coin, officially known as the Liberty Head double eagle, was minted by the United States from 1849 until 1907. The 1865 version features a design by engraver James B. Longacre, showcasing a portrait of Lady Liberty on the obverse and an eagle with a shield on the reverse. Composed of 90% gold and 10% copper, these coins weigh approximately 33.4 grams and contain about 0.9675 troy ounces of pure gold. Collectors highly value the $20 Liberty Gold coins for their historical significance and gold content, with specific years, such as 1865, holding particular importance due to their lower mintage figures and condition rarity.
