What is high relief coin
The United States Mint issued the 2009 Ultra High Relief Double Eagle Gold Coin to fulfill the artistic vision of the sculptor Augustus Saint Gaudens. His original vision for the $20 gold piece could not be realized during his time, but utilizing 21st century technology, the Mint was able to faithfully recreate a masterpiece.
To produce the 2009 UHR Double Eagle, the original Saint Gaudens coin plasters were digitally mapped. A number of minor updates were performed, which included changing the date to “MMIX” (2009), increasing the number of stars from 46 to 50, and adding the motto “In God We Trust” on the reverse of teh coin. A small border was added to both sides of the coin to create a more consistent edge.
Each coin was struck in 24 karat gold, which is more malleable than the 90% gold composition that was used for circulating gold coins. The diameter of the recreation is 27 mm with a thickness of 4 mm. All coins were stuck with an uncirculated finish, which can appear proof like for some examples.
