1849-1907 Liberty Double Eagle
The Liberty Head Double Eagle, also known as the Coronet Double Eagle, was a $20 gold coin issued by the United States Mint from 1849 to 1907. It was designed by James Longacre and featured Liberty with a coronet on the obverse and an eagle on the reverse. Mint marks were used to indicate the mint of origin and are typically found on the reverse side of the coin, either below the eagle's tail or near the denomination.
