The 40th Anniversary Gold Eagle Proof Set — Four Denominations in Perfect PF70
The 2026 American Gold Eagle Proof Set marks the 40th anniversary of the Gold Eagle program, first introduced by the United States Mint in 1986. Issued as a four-piece set encompassing the full denomination range — 1 oz ($50), 1/2 oz ($25), 1/4 oz ($10), and 1/10 oz ($5) — this set represents the complete expression of the Gold Eagle series in a single proof presentation. Struck at the West Point Mint, each coin is composed of 22-karat gold (.9167 fine) and finished to proof specifications, with deep mirror fields and frosted devices that define the series' finest annual issues.
Advanced Release — NGC PF70 Across All Four Coins
Each coin in this set has been certified PF70 by the Numismatic Guaranty Company — the highest grade attainable for a proof coin — with no post-production imperfections visible under 5x magnification. The Advanced Release designation recognizes acquisition among the earliest available examples from this anniversary issue. Assembling a complete four-coin proof set where every denomination reaches PF70 is a meaningful achievement; the 1/10 oz in particular can be the most challenging to certify at this level due to its smaller diameter and the precision required to achieve flawless surfaces.
The Modern Numismatic Masterpieces Book Label
This set is housed in NGC holders carrying the Modern Numismatic Masterpieces label — a designation tied to Stephen Pfeil's landmark reference work, Modern Numismatic Masterpieces: Rare U.S. Coins of the 20th and 21st Century, published in October 2025 and officially added to the American Numismatic Library upon release. The book, with forewords contributed by Anna Escobedo Cabral and Stephanie Sabin, has become a foundational text for collectors focused on 20th and 21st century U.S. coinage. The NGC label ties this anniversary proof set directly to that body of scholarship.
Autographed by Anna Escobedo Cabral, 42nd Treasurer of the United States
This set bears the personal autograph of Anna Escobedo Cabral, who served as the 42nd Treasurer of the United States from 2004 to 2009 under President George W. Bush. Her signature appeared on all Federal Reserve Notes issued during her tenure, connecting her autograph to the living history of American currency. On a four-piece gold proof set issued in the 40th anniversary year of the Gold Eagle program, that connection carries particular resonance. Global Coin holds a limited number of these NGC-certified, book-label, Cabral-autographed anniversary sets.
