Description

The 1857 (O) Seated Liberty Half Dollar is a half dollar produced at the New Orleans Mint as part of the Seated Liberty Half Dollars 1839-1891 series. The U.S. Mint produced 818,000 examples, making this ranked 2nd of 3 mint variants by mintage, with 28% of 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 New Orleans Mint, which operated from 1838 to 1909 and produced coins prized for their historical Southern provenance. Estimated market value ranges from $83 to $4.3K 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 #6291.
