The American Gold Eagle bullion coin was authorized under the Gold Bullion Coin Act of 1985 and first issued in 1986. Since its inception, it has become one of the most trusted and widely traded gold bullion coins in the world because the U.S. government guarantees its weight, gold content, and purity, even though its market value generally follows the spot price of gold.
The 1991 issue is struck in Brilliant Uncirculated (BU) condition — meaning it was minted with original luster and crisp details but may show only minimal handling marks typical of bullion coins designed for physical gold ownership rather than graded collectibles.
🪙 Design & Specifications
Gold Content & Purity:
• Contains 1 troy ounce of actual gold content in .9167 fine (22 karat) gold, alloyed with copper and silver for durability.
Finish:
• Brilliant Uncirculated (BU) — original mint luster with crisp detail typical of bullion strikes.
Obverse Design:
• Depicts Lady Liberty holding a torch and olive branch — adapted from Augustus Saint-Gaudens’ 1907 Gold Double Eagle design, one of the most celebrated in U.S. numismatic history.
Reverse Design (Type 1):
• Features the classic “family of bald eagles” — a male eagle in flight carrying an olive branch above a nest with a female eagle and eaglet. This reverse was used on bullion American Gold Eagles from 1986 through 2020.
Legal Tender:
• $50 U.S. face value, backed by the United States government — though its market price is driven primarily by gold content.
Dimensions:
• Diameter: ~32.7 mm
• Thickness: ~2.87 mm
• Gross Weight: ~33.93 g (contains 1 troy ounce of gold).
Mint Mark:
• Bullion American Gold Eagles generally do not display a mint mark on the coin’s face; they are produced by the U.S. Mint bullion program (often at the West Point Mint).
