The American Gold Eagle is an official gold bullion coin of the United States.  These coins are guaranteed by the U.S. government to contain the stated amount of actual gold weight in troy ounces.  The obverse design sculpted by Augustus Saint-Gaudens feature a full length figure of Lady Liberty with flowing hair, holding a torch in her right hand and an olive branch in her left, with the capitol building in the background. The reverse design, by sculptor Miley Busiek, features a male eagle carrying an olive branch flying above a nest containing a female eagle and her hatchlings.  The United States Mint also produces a proof version for coin collectors. These coins are for the most part produced at the West Point Mint in West Point, New York and carry the mints mark ("W") beneath the date. Gold Eagles minted 1986-1991 are dated with Roman numerals. In 1992, the U.S. Mint switched to Arabic numbers for dating Gold Eagles. The 1/10, 1/4, and 1/2 troy oz coins are identical in design to the one troy ounce coin.
