Struck over a century ago at the San Francisco Mint, the 1903-S Liberty Head $20 gold pieces (or double eagles) are large, precious collectibles from early 20th-century America. These handsome coins bear James B. Longacre's famous portrait of Liberty wearing a coronet inscribed LIBERTY. The fascinating reverse depicts an eagle with a shield, the motto IN GOD WE TRUST encircled with stars, and the denomination stated as TWENTY DOLLARS.
