The 1991 release of Silver American Eagle coins was one of contrasting fortunes between the bullion and proof versions of the coin. While one was on the rise, hitting a mark that wouldn’t be seen again for eight years, the other was sinking in popularity. Right now, the 1991-S Proof Silver American Eagle coin is available for purchase in perfect condition from

Silver American Eagle sales in 1991 surged to a new high for the third-consecutive year for the bullion version of the coin. After dropping from 11.4 million to 5.0 million in 1988, the coin had steadily grown to reach 7.19 million in 1991.

On the other hand, the 1991 Proof Silver American Eagle ushered in an era of declining mintage for the collector’s version. After two years of growth, the Proof Silver American Eagle dropped more than 180,000 in number from 695,000 in 1990 to 511,925 in 1991. This was just the beginning though as the Proof Silver American Eagle shed mintage numbers for the next three years, eventually bottoming out at an all-time low in 1994.

The drop in popularity of and demand for the Proof Silver American Eagle was the result of spot value of silver holding at lower levels, driving more investors to the bullion version of the coin instead. The average price of silver throughout 1991 was $4.05, with a low point of $3.61 per ounce.

All 1991-S Proof Silver American Eagle coins available here on have PF70 grades from the NGC. Each coin exhibits full, original luster from the mint and lacks any detracting flaws on its surfaces.

UCAM, or ultra-cameo, is a term that defines proof coins with an exceptional finish. The design set of each of these coins has a strong, frosted matte finish. The background field contrasts that with a deeply-mirrored, clear finish.
