United States Mint, Philadelphia. Less than two dozen of these coins were struck. This kind of relief was never intended for a circulating coin, because it took nearly a dozen passes through the press to achieve. We should instead see these marvelous coins as testimony to the human spirit and to human curiosity: just how much relief could you obtain, and how long would it take to create it?
This ultra high relief twenty has pedigree as well as beauty in its favor. Presdient Theodore Roosevelt gave it to his daughter as a Christmas present in 1907. Augustus Saint-Gaudens had presented it to the president, and it may have been the first piece struck. Roosevelt's daughter donated this coin to the Smithsonian in 1961.
