Description

The 1866 Seated Liberty Half Dime is a dime produced at the Philadelphia Mint as part of the Seated Liberty Half Dimes 1837-1873 series. With a mintage of 10,000, this is an extremely rare issue — the scarcer of two mint variants, with 8% 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. Minted during Reconstruction and the Gilded Age, as the nation healed from civil war and debated the role of silver and gold in the monetary system. Struck at the original U.S. Mint facility, in continuous operation since 1792. Estimated market value ranges from $409 to $1.5K 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 #4388.
