Description

The 1857 (S) Seated Liberty Half Dollar is a half dollar produced at the San Francisco Mint as part of the Seated Liberty Half Dollars 1839-1891 series. The U.S. Mint produced 158,000 examples, making this the lowest mintage among 3 mint variants, representing only 5% of total production. The obverse features Liberty seated on a rock, holding a pole surmounted by a Phrygian liberty cap in her left hand and a shield inscribed LIBERTY in her right and the reverse displays a heraldic eagle with shield on breast, olive branch and arrows in talons, with a banner reading E PLURIBUS UNUM. Struck during the California Gold Rush era, when vast quantities of western gold transformed the American economy and led to new denominations. Struck at the San Francisco Mint, established during the California Gold Rush and now primarily producing proof and collector coins. Estimated market value ranges from $208 to $17K depending on grade and condition. Struck in 90% silver, 10% copper, weighing 12.4 grams, 30 mm in diameter, with a reeded edge. Cataloged as PCGS #6292.
