Item: 1988-S American Silver Eagle Proof Mint: San Francisco (“S” Mint Mark) Composition: 1 Troy Ounce. 999 Fine Silver Packaging: Original Government Packaging (OGP) – Purple Velvet Box & COA? About This Coin: Up for sale is a stunning 1988-S Proof American Silver Eagle. This is the third year of the series and remains a favorite among collectors for its classic design and historical significance. This coin features the iconic “S” mint mark on the reverse and a beautiful mirror-like proof finish. Condition Notes:? Finish: Deep mirrored fields with sharp, frosted devices (Cameo effect). Clarity: The fields are exceptionally clear with no significant “milky” hazing often seen in 1980s silver proofs. Packaging: Includes the original purple velvet clamshell case and the United States Mint Certificate of Authenticity (COA). I use extra padding and sturdy outer packaging to ensure the original mint box arrives in excellent condition.
