Product Description

In 1988, the Proof American Silver Eagle witnessed a decline in demand after the initial two years of fervent buying. It’s a common trend for collectible coins to experience peak demand during their first releases, and the Proof American Silver Eagle is no exception. Now, discover the excellence of 1988-S 1 oz Proof American Silver Eagle coins in flawless condition, available for purchase at BGASC.

All the 1988-S 1 oz Proof American Silver Eagle Coins presented here are in impeccable condition. PF70 coins exhibit full, original mint luster, devoid of any detracting flaws. UCAM, short for ultra-cameo proof, signifies a coin with vivid, frosted designs contrasting against deeply-mirrored, clear fields.


On the obverse of the 1988-S Proof American Silver Eagles is the iconic Walking Liberty design, conceived in 1916 by Adolph A. Weinman. This breathtaking depiction of Liberty in left-profile relief symbolizes her journey towards the sun on the horizon, draped in the American flag.


Flipping to the reverse side, the 1988-S 1 oz Proof Silver Eagle Coin displays an image of the heraldic eagle. Revitalized for this collection in 1986 by John Mercanti, the design features the bald eagle in front-facing relief with the US national shield, the arrows of war, and the olive branch of peace.


In numismatic series, the earliest dates often hold the greatest allure for collectors. The debut of the Proof Silver Eagle in 1986 remains the highest-minted coin in the program’s history. Hence, it’s unsurprising that the 1988 release experienced a decline in demand, nearly 1 million coins less than 1986.
