The original Saint-Gaudens Double Eagle mostly gold coin was minted by the United States Mint from 1907-1933. In 1904, President Theodore Roosevelt asked the artist Saint-Gaudens to design the Double Eagle gold coin. It was made with 90% gold / 10% copper, weighed .96750 Troy ounces, and had a face value of $20 USD. The current cost of gold per ounce is $1,978 USD - as a collectors coin, an original gold Double Eagle coin sold in 2002 for $7,590,020 USD (Source).
The Lady Liberty Side of the silver remake is very similar to the original, but the original has the minted year at the bottom right of the coin, and the original features the White House at the bottom left. As you can see, the Eagle Side is very different from the original - the eagle is flying to the left, "UNITED STATES OF AMERICA TWENTY DOLLARS" is along the top curve of the coin, and the sun can be seen at the bottom with "IN GOD WE TRUST". The 1907 original Double Eagle does not have "IN GOD WE TRUST" at the bottom, congress was outraged, it was added for the 1908-1933 coins.
The Saint-Gaudens Double Eagle remake from SilverTowne Mint is a 1oz .999 fine silver round, featuring the Saint-Gaudens designed Lady Liberty front (Source).
The Liberty Side of the coin features the Saint-Gaudens Lady Liberty design, she's walking forward to the edge of a cliff and out of the sunlight rays. She has an olive branch in one hand, a torch in the other - stars are along the outside curve of the coin, representing the states.
The eagle side features an eagle perched onto and clutching an olive branch with it's talons, facing to the left. Along to top curve is the text "ONE OUNCE .999 FINE SILVER", at the bottom is the SilverTowne text and logo.
This Saint-Gaudens Double Eagle is another classic remake from SilverTowne Mint - another fine silver round for the stack.
