Description
The 1870 (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 only 1, this is an extremely rare issue. 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, while the reverse displays an agricultural wreath enclosing the denomination. Designed by James Barton Longacre. Struck in 90% silver, 10% copper, weighing 1.24 grams, 15.9 mm in diameter, with a reeded edge. Cataloged as PCGS #4397. The Seated Liberty Half Dime was the final five-cent silver coin. Transitional varieties with and without arrows at the date are collected by type. The 1870-S is a rarity with only one known example. New Orleans and San Francisco mint issues carry premiums.
