Description

The 1866 Proof Seated Liberty Dollar - No Motto is a proof dollar struck at the Philadelphia Mint, part of the Seated Liberty Dollars 1840-1873 series. With a mintage of 2, this is an extremely rare issue — the lowest mintage among 3 mint variants, representing only 0% 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 a heraldic eagle with shield on breast, olive branch and arrows in talons, with a banner reading E PLURIBUS UNUM. 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. 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 $4.8K. Struck in 90% silver, 10% copper, weighing 26.73 grams, 38.1 mm in diameter, with a reeded edge. Cataloged as PCGS #87009.
