The U.S. Mint has made history once again with the release of the final “S” Proof American Silver Eagle. Struck at the San Francisco Mint, this special coin marks the end of a series that has been a favorite of collectors for decades.
With its unique design, limited mintage, and high demand, this last edition is already being seen as a must-have for coin enthusiasts.
What Makes the “S” Proof Special
The San Francisco Mint has produced Proof Silver Eagles for years, but what makes this release stand out is the “S” mintmark. This small letter shows where the coin was made and gives it extra importance.
Compared to the West Point “W” version, San Francisco proofs usually come with lower mintage numbers, making them more desirable.

Classic Design That Endures
The American Silver Eagle series, launched in 1986, has always featured Adolph A. Weinman’s Walking Liberty design on the obverse (front).
Liberty is shown walking forward, carrying oak and laurel branches, with the U.S. flag draped over her shoulders. The inscriptions include “LIBERTY,” “IN GOD WE TRUST,” and the year “2025.”
In 2021, the Mint updated the design to sharpen the details and better reflect the original artwork using modern technology.
Reverse Design
The reverse (back) shows an eagle landing with an oak branch in its talons. This design by Emily Damstra and sculpted by Michael Gaudioso replaced the older heraldic eagle that had been used for decades. The inscriptions read:
- “UNITED STATES OF AMERICA”
- “E PLURIBUS UNUM”
- “1 OZ. FINE SILVER”
- “ONE DOLLAR”
