The Proof American Eagle Silver Coins debuted in 1986. The most popular dates in proof collections are often special anniversary releases, unique strikes, and the earliest coins in the collection. The 1988 coin is unique in that it is from early in the series and has a low mintage, making certified versions of it still available today a hot commodity. Today, you have the opportunity to purchase 1988-S Proof American Eagle 1 oz Silver Coins online at Provident Metals in perfect condition.

On the obverse side of 1988-S Proof American Eagle 1 oz Silver Coins, you will find the effigy of Lady Liberty created in 1916 by Adolph A. Weinman. This vision of Liberty showcases her figure in full left-profile relief as she walks toward the sun on the horizon. The American flag is draped over her shoulders and she carries branches of oak and laurel in her left hand.


The reverse field on 1988 Proof American Eagle 1 oz Silver Coins bears the heraldic eagle of the United States of America. This iconic design was modernized in 1986 for the debut of this collection by John Mercanti. He developed a national seal design with a powerful American bald eagle clutching the arrows of war and olive branch of peace. Above its head is a tightly-packed triangular cluster of 13 stars.


Proof American Eagle Silver Coins are produced to meet collector demand and the series has not had mintage caps since the early years of availability. The 1988 Proof American Eagle 1 oz Silver coin sold just 557,370 coins. That was 350,000 less than the 1987 coin and 60,000 less than the 1989 coin.


These 1988-S Proof American Eagle 1 oz Silver Coins are available to purchase in perfect condition. PF70 coins have full, original mint luster and no detracting flaws. The included UCAM label stands for ultra-cameo and indicates the coins have strong, frosted designs with deeply-mirrored, clear fields.
