$20 Liberty Gold Double Eagles

The $20 Liberty Head Double Eagle is one of the most significant series in American gold coinage, struck by the United States Mint from 1849 through 1907. Composed of .900 fine gold and weighing 33.436 grams (approximately 0.9675 troy oz of pure gold), the double eagle was the highest face-value coin produced for regular circulation during the nineteenth century. The series encompasses two major design subtypes: the Type I (1849–1866), featuring no motto on the reverse; the Type II (1866–1876), which added IN GOD WE TRUST above the eagle; and the Type III (1877–1907), distinguished by the reverse legend change from TWENTY D. to TWENTY DOLLARS. Liberty's coroneted portrait on the obverse was designed by James B. Longacre, the Mint's Chief Engraver at the time of the coin's introduction.\n\nWithin numismatics, the Liberty Double Eagle holds a distinctive position as a workhorse of commerce and international trade throughout the Gilded Age. Examples were produced at multiple mint facilities — Philadelphia, San Francisco, Carson City, New Orleans, and Denver among them — resulting in a wide range of mintages and corresponding collectibility by date and mintmark. Circulated grades (VF through AU) are the most commonly encountered, though certified Mint State examples exist across the series and command considerable collector interest. The Carson City (CC) issues are particularly sought after among date-and-mintmark collectors.\n\nOn CoinDuffle, buyers will find $20 Liberty Double Eagles spanning the full run of the series, offered by a range of professional dealers. Listings include raw circulated examples, problem-free AU survivors, and NGC- or PCGS-certified Mint State coins. Both individual date acquisitions and type-coin representatives of each subtype are regularly available, making this page a resource for specialist date collectors and type collectors alike.
