As a foundational denomination of American coinage, the gold double eagle signifies the power of the once-mighty United States dollar. Displaying both the Liberty and Saint Gaudens obverse designs, this near-one-ounce gold denomination is a staple for type coin collections worldwide. Twenty-dollar gold pieces were minted between 1850 and 1933. Like all U. S. gold coinage, they were composed of 90% gold and 10% copper for durability. Southgate Coins offers an extensive selection of double eagles. Because of the volatile price of gold, our company posts only a fraction of our available supply of gold coins. It is best if you will call to check what we have in inventory and get updated prices. (Click here to view gold double eagles from the Carson City Mint.)
