A $20 Liberty Head Double Eagle, minted between 1870 and 1893: • Bears the rarely seen “CC”(Carson City)mint mark, found on less than 1% of Liberty Head Double Eagles. • Contains almost a full ounce of pure gold, in a scarce coin spurred into existence by the California gold rush. • Features designer James B. Longacre’s portrait of Lady Liberty adorned with a coronet, notable for its classically inspired grace and simplicity.
