Every 1991-S 1 oz Proof American Silver Eagle Coin at BGASC attains perfection, certified with a PF70 grade by the NGC, boasting full mint luster and an absence of detracting flaws. Achieving a UCAM (ultra-cameo) designation involves a strong, frosted matte finish against a deeply-mirrored, clear background field, creating a visually striking appearance.

The obverse of 1991-S Proof American Silver Eagles features the timeless Walking Liberty image, crafted by Adolph A. Weinman in 1916.


Meanwhile, the reverse of the 1991-S 1 oz Proof Silver Eagle Coin showcases the heraldic eagle, refined by US Mint Chief Engraver John Mercanti in 1986.


Proof American Silver Eagle coins have been cherished since 1986, annually available in a one-ounce weight. The 1991-S edition, with a total mintage of 511,924, is a rare find with perfect PF70 grades and a UCAM designation.
