Description

The 1870 (S) Seated Liberty Dollar is a dollar produced at the San Francisco Mint as part of the Seated Liberty Dollars 1840-1873 series. With a mintage of 15, this is an extremely rare issue — the lowest mintage among 3 mint variants, representing only less than 1% 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. The 1870-S is a legendary rarity with approximately nine known examples, possibly struck for the San Francisco Mint cornerstone ceremony. 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 $188K to $2174K depending on grade and condition. Struck in 90% silver, 10% copper, weighing 26.73 grams, 38.1 mm in diameter, with a reeded edge. Cataloged as PCGS #6965.
