Description
The 1870 Proof Liberty Head Half Eagle is a proof Gold Half Eagle struck at the Philadelphia Mint, part of the Liberty Head Half Eagles 1839-1908 series. With a mintage of 35, this is an extremely rare issue — the lowest mintage among 4 mint variants, representing only less than 1% of total production. The obverse features Liberty facing left wearing a coronet inscribed LIBERTY and the reverse displays a heraldic eagle with shield on breast, olive branch and arrows in talons, with a banner reading E PLURIBUS UNUM. First Carson City half eagle. 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. Struck at the original U.S. Mint facility, in continuous operation since 1792. Estimated market value is approximately $35K. Struck in 90% gold, 10% copper, weighing 8.36 grams, 21.65 mm in diameter, with a reeded edge. Cataloged as PCGS #8465.
