1990-S American Silver Eagle $1 NGC PF 70 Ultra Cameo

The 1990-S American Silver Eagle $1, certified PF 70 Ultra Cameo by the Numismatic Guaranty Corporation, represents a flawless example from the San Francisco Mint's proof American Silver Eagle series. Struck in 0.999 fine silver at 1 troy oz, this coin carries a face value of one dollar and belongs to a series the U.S. Mint has produced annually since 1986. The PF 70 designation from NGC denotes a perfect proof specimen with no post-production imperfections of any kind visible under 5x magnification, while Ultra Cameo signifies the maximum possible contrast between the deeply frosted sculptural devices and the mirror-polished fields — a combination that produces the dramatic black-and-white cameo effect for which proof Silver Eagles are prized. The obverse presents Adolph A. Weinman's majestic Walking Liberty figure, originally created for the 1916 Walking Liberty Half Dollar and widely regarded as one of the finest designs in American coinage history. The reverse, designed by John Mercanti, features a heraldic bald eagle with a shield on its breast, clutching an olive branch and arrows, with 13 stars above and the inscription "1 OZ. FINE SILVER — ONE DOLLAR." The coin is encapsulated in NGC's sonically sealed slab, bearing certification number 3917154-014.
