The obverse has appeared on American gold bullion coinage issued since 1986. Saint-Gaudens’s original design was reused, with two stars added next to the two which Barber had added in 1912, recognizing the admission of Alaska and Hawaii to the Union. Saint-Gaudens’s reverse was not used, yielding its place to sculptor Miley Busiek’s depiction of a family of eagles.
In 1907, the Mint had experimented by striking about two dozen pieces of the same weight as the double eagle, bearing Saint-Gaudens’s design, but which had a smaller, thicker planchet. These “checker” pieces were destroyed (except two placed in the Mint’s coin collection) when it was discovered that the consent of Congress was needed to change the diameter of any coin. In 2009, the Mint struck a similar piece in .999 gold, using Saint-Gaudens’s original ultra high relief design for both sides of the coin, though modified to a 50-star obverse. These pieces contain one ounce of gold, slightly more than the original double eagle.
