Description

The 1864 (S) Seated Liberty Half Dime is a dime produced at the San Francisco Mint as part of the Seated Liberty Half Dimes 1837-1873 series. With a mintage of 90,000, this is an extremely rare issue — the higher-mintage of the two mint variants, representing 65% 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 an agricultural wreath enclosing the denomination. Produced during the Civil War, when coin hoarding caused severe shortages and the Mint experimented with new compositions to keep coins in circulation. 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 $105 to $2.3K depending on grade and condition. Struck in 90% silver, 10% copper, weighing 1.24 grams, 15.9 mm in diameter, with a reeded edge. Cataloged as PCGS #4385.
