The Liberty Head Double Eagle is a twenty-dollar gold coin that was produced by the United States Mint from 1849 to 1907. The coin features a portrait of Lady Liberty on the obverse and a bald eagle with a shield on the reverse. The 1889-S (San Francisco) variant is particularly notable among collectors due to its limited mintage and the scarcity of high-quality examples, making it one of the key dates in the Double Eagle series. Its composition consists of 90% gold and 10% copper, weighing 33.44 grams with a diameter of 34 mm.
