The United States first official gold coins debuted in 1795 two years after the copper coinage. The delay was a result of Mint Officials inability to obtain the proper bond that allowed them to handle precious metals such as gold and silver.
Early U.S. Mint gold coins included:
The Draped Bust $2.5 Quarter Eagle debuted in 1796
The Draped Bust $5 Half Eagle debuted in 1795
The Draped Bust $10 Eagle debuted in 1795
The U.S. Mint stopped producing the $10 Eagle in 1804 and didn’t resume until 1838.
As a result of the Californai gold rush (1848) new gold coins were launched. The $20 Double Eagle in 1850, the G$1 Coin in 1849, the Three Dollar Gold Coin in 1854 and the $4 Gold Coin known as the Stella in 1879.
The gold Eagle denominations followed the same designs as other U.S. coins with the Draped Bust and the Capped Bust and then unique to U.S. Gold Coins the Classic Head, The Liberty, the Indian and the $20 Saint Gaudens.
