The Math / Science
A U.S. Gold Eagle is a gold bullion coin minted by the United States Mint, first introduced in 1986. Made of 91.67% pure gold (22 carats), it contains a specified amount of pure gold, with the balance being copper and silver for durability. Available in 1 oz, 1/2 oz, 1/4 oz, and 1/10 oz denominations, its weight and gold content are guaranteed by the U.S. government. The obverse features Augustus Saint-Gaudens’ depiction of Lady Liberty, while the reverse shows a bald eagle design by Miley Busiek or Jennie Norris (post-2021). Primarily an investment coin, its value is tied to the spot price of gold plus a premium, and it holds legal tender status, though its market value far exceeds its face value.
