Description

The 1878 (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. With a mintage of 12,000, this is a scarce 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. Struck during the Gilded Age of rapid industrialization and the great silver debates, when monetary policy shaped elections and economic destiny. 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 $39K to $147K depending on grade and condition. Struck in 90% silver, 10% copper, weighing 12.5 grams, 30 mm in diameter, with a reeded edge. Cataloged as PCGS #6360.
