A Trifecta of Modern Rarity
Elevate your collection with a coin that represents a "perfect storm" of numismatic rarity: the 1987 "Reverse Struck-Thru" American Silver Eagle, signed by its designer, John Mercanti. It is nearly impossible to find a coin that checks more boxes for the advanced collector. It begins as a key second-year-of-issue 1987 Silver Eagle. It is then dramatically transformed by a major mint error. Finally, it is personally autographed by the very artist who designed the side of the coin where the error occurred. Preserved in superb MS69 condition, this coin is not just a treasure; it's a multi-layered story of history, artistry, and pure chance.
Exquisite Design
This coin features the classic American Silver Eagle designs, but with a dramatic flaw and a legendary signature that elevate it to an entirely new level.
Obverse: The obverse showcases Adolph A. Weinman’s timeless "Walking Liberty" design. Lady Liberty strides confidently toward the dawn, her iconic figure rendered in sharp, lustrous detail, just as it appeared in the program's second year.
Reverse: The reverse features the powerful Heraldic Eagle design created by John M. Mercanti. This is the centerpiece of this coin's incredible story. The iconic design is permanently and uniquely altered by the "Struck-Thru" error, and the holder containing it is autographed by Mercanti himself, creating an unbroken link between the artist, his art, and the unique error that makes this coin one-of-a-kind.
Why Collect This Coin?
The case for this coin’s elite status is undeniable. It achieves an incredible trifecta of collector appeal: a Major Error, a Key Early Date, and a Designer's Signature. The certified "Struck-Thru" error makes it a unique specimen. Its 1987 date places it in the foundational era of the Silver Eagle program. The John Mercanti signature provides a direct, personal link to the coin's creation. Finding any one of these attributes on a high-grade coin is desirable; finding all three together is extraordinary.
Detailed Overview
