WEIGHT IN GOLD 18 K : 22.04 GR WEIGHT IN SILVER 925 : 16.55 GR The $10 Liberty Eagle Gold Coin was struck by the United States Mint from 1838 through 1907. The Gold Liberty Eagle's obverse was designed by Christian Gobrecht and is also known as the Coronet head eagle due to the artist's left-facing portrait of Lady Liberty in a coronet cap inscribed with LIBERTY. The $10 Gold Liberty Eagle's reverse side features a heraldic eagle with wings outstretched, a cluster of arrows in one claw and an olive branch in the other. Also inscribed on the reverse is, UNITED STATES OF AMERICA and TEN D.. This design was used for nearly 70 years with only a slight change in the portrait in 1839, and the addition of the motto IN GOD WE TRUST banner on the reverse side in 1866. $10 Liberty Eagle Coins without the In God We Trust banner on the reverse side are referred to as No Motto coins, and the coins that were minted with the banner are known as With Motto. The gold Liberty Head Eagle coins that were produced at the U.S. mints in Carson City (CC), Denver (D), New Orleans (O), and San Francisco (S) all have a mint mark that can be found on the reverse side just beneath the eagle. Gold $10 Liberty Head eagles that were minted at the U.S. Philadelphia mint do not contain a mint mark at all.
