A Double Eagle is a $20 gold coin issued by the United States Mint between 1849 through 1933. Double Eagles are struck from 33.44 grams of .900 fine gold. The coin was first minted in 1849 and designed by James B. Longacre, the fourth Chief Engraver of the United States Mint. This first design, known as the Liberty Head design, was issued from 1849 to 1907.
The most famous Double Eagle is the Saint-Gaudens Double Eagle which was issued from 1907 to 1933. This second design in the series was created by Augustus Saint-Gaudens and features a full-length figure of Liberty on its obverse side, as well as an eagle in flight on its reverse side.
Originally issued into circulation, today, these coins are sought after by many coin collectors due to their historical significance and beauty.
