Most Popular US Twenty Dollar Gold Coins
Twenty dollar gold coins minted in the United States are commonly referred to as the Double Eagle. These gold coins are of two types, one with the Liberty design and the other with the Saint Guadens’ design.
•   Liberty Twenty Dollar Gold Coins
These coins were minted in three different varieties at different time periods, which are:

•   “Twenty Dâ€, Liberty Head Coin with no motto, minted between 1849 and 1866.

•   “Twenty Dâ€, Liberty Head Coins with motto minted between 1966 and1876.

•   “Twenty Dollarsâ€, Liberty Head Coins with motto minted between 1877 and 1907.
These coins were designed by James B. Longacre, US Mint’s engraver. They were not produced for daily exchange purposes because $20 was a huge amount for the time when these coins were minted. These coins served the purpose of paying off debts to foreign investors as well as for the purpose of bank transfers. These coins have a gross weight of 33.346 grams with a diameter of 34 mm. They are made up of 90% pure gold content with 10% alloy of copper.
