The "Double Eagle" is a famous gold coin that was minted in the United States, primarily in the late 19th and early 20th centuries. It features a design by Augustus Saint-Gaudens, showcasing a majestic eagle in flight on one side and Lady Liberty on the other. The coin is valued for both its gold content and its historical significance. Originally produced in denominations of $20, the Double Eagle became a symbol of wealth and prosperity. The most notable version is the 1933 Double Eagle, which was never officially released for circulation and is now considered one of the most valuable coins in the world.
