The 1988 Proof Silver Eagle represented the third year of release for the collectible version of the American Silver Eagle bullion coin. As experienced with other modern collector series, a decline in interest occurred as some of the early excitement faded. This led to reduced sales and resulting mintage of 557,370.
This mintage level was down significantly from the 1.4 million proof coins sold for the first year of release in 1986 and also down from the prior year sales of just over 900,000. Despite the drop in mintage, the 1988 Proof Silver Eagle does not carry a premium above the more abundant earlier issues of the series.
Pricing for the 1988 American Silver Eagle Proof Coins remained unchanged from the prior year at $23.00 each. The coins were sold directly by the US Mint to collectors and included in protective and decorative packaging. This consisted of a plastic capsule, purple colored velvet display case, purple outer box, and a certificate of authenticity signed by the Director of the United States Mint.
The price of silver began the year 1988 priced at $5.88 per ounce and quickly spiked to $7.80. The price experienced a sharp and then general decline through the remainder of the year and eventually closed at just over $5.00 per ounce.
