Description

The 1857 (O) Seated Liberty Half Dime is a dime produced at the New Orleans Mint as part of the Seated Liberty Half Dimes 1837-1873 series. With a mintage of 1.4 million, this is a less common issue — the scarcer of two mint variants, with 16% 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 an agricultural wreath enclosing the denomination. 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 $32 to $614 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 #4366.
