Description

The 1866 (S) Liberty Head Eagle - Motto is a Gold Eagle produced at the San Francisco Mint as part of the Liberty Head Eagles 1838-1907 series. With a mintage of 11,500, this is a scarce issue — the highest mintage among 3 variants, accounting for 48% of the year's 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. Struck at the San Francisco Mint, established during the California Gold Rush and now primarily producing proof and collector coins. Estimated market value ranges from $4.2K to $53K depending on grade and condition. Struck in 90% gold, 10% copper, weighing 16.7 grams, 26.8 mm in diameter, with a reeded edge. Cataloged as PCGS #8650.
