1988-S Proof American Silver Eagle PF-70 NGC

---

The 1988 proof silver dollar stands as an early milestone in one of the most celebrated precious metal series from the United States, which first debuted in 1986. Struck at the San Francisco Mint, this coin bears the distinctive S mint mark, signifying its origin and the specialized proof manufacturing process that gives the piece its highly reflective, mirror-like fields and frosted details. The obverse features a graceful depiction of Lady Liberty wrapped in the folds of the American flag. She is shown in stride toward a rising sun peeking over a mountain ridge. This side of the coin carries the legible inscriptions of the year 1988 and the national motto, IN GOD WE TRUST. On the reverse, a powerful heraldic eagle is displayed beneath a cluster of 13 small stars. The inscriptions on this side confirm its status as official United States currency, reading UNITED STATES OF AMERICA along with the denomination of ONE DOLLAR. The coin is composed of exactly one troy ounce of 0.999 fine silver, as noted by the inscription 1 OZ. FINE SILVER, and features the traditional motto E PLURIBUS UNUM.
