Description
The 1866 Proof Silver Three Cent Piece is a proof cent struck at the Philadelphia Mint, part of the Silver Three Cent Pieces 1851-1873 series. With a mintage of 725, this is an extremely rare issue — the scarcer of two mint variants, with 3% of total production. The obverse features a six-pointed star enclosing a Union shield and the reverse displays a Roman numeral III (three) within a large letter C. 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 $1.1K. Struck in 90% silver, 10% copper, weighing 0.75 grams, 14.3 mm in diameter, with a plain edge. Cataloged as PCGS #3716.
