The 1909/8 overdate was created when the Mint used a 1908 hub and a 1909 hub to create a new die. Its believed that only one die was created to stike the approximate 80,000 overdate coins. PCGS population for the MS63 is only 457.
The Saint-Gaudens Double Eagle was produced by the U.S. Mint from 1907 to 1933. The coin's name, derived from its designer, sculptor Augustus Saint-Gaudens was commissioned by President Theodore Roosevelt in 1904 to beautify American coinage. The coin is often considered to be the most beautiful of U.S. gold coins and features a standing Miss Liberty lighting the way to freedom by holding a torch as the dawn rises over the Capitol. The reverse is a majestic flying eagle with the twenty-dollar denomination.
The coins were met with controversy when originally released because the design lacked the words, "In God We Trust." An outraged Congress quickly ordered the motto to appear on the coin and coins minted after 1908 feature the slogan. The Saint-Gaudens gold coins are U.S. legal tender and are not medallions or other reproductions.
