Description
The 1866 Proof Liberty Head Eagle - Motto is a proof Gold Eagle struck at the Philadelphia Mint, part of the Liberty Head Eagles 1838-1907 series. With a mintage of 30, 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. Motto "IN GOD WE TRUST" added to the reverse, creating a major type distinction. 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 $44K. Struck in 90% gold, 10% copper, weighing 16.7 grams, 26.8 mm in diameter, with a reeded edge. Cataloged as PCGS #8806.
