Description
The 1877 Proof Seated Liberty Twenty Cent is a proof cent struck at the Philadelphia Mint, part of the Seated Liberty Twenty Cents 1875-1878 series. With a mintage of 510, 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 and the reverse displays an eagle with outstretched wings. Struck during the Gilded Age of rapid industrialization and the great silver debates, when monetary policy shaped elections and economic destiny. As a proof issue, this coin was struck multiple times on specially prepared polished planchets using polished dies, producing mirror-like fields and frosted design elements prized by collectors. Estimated market value is approximately $11K. Struck in 90% silver, 10% copper, weighing 5 grams, 22 mm in diameter, with a plain edge. Cataloged as PCGS #5305.
