Aided by advancements in technology, the United States Mint can produce, in quantity, the ultra high relief coin envisioned, but never fully realized, by Roosevelt and Saint–Gaudens in 1907. Through 21st century technology, original Saint–Gaudens coin plasters were digitally mapped by the United States Mint. The Saint–Gaudens sculpture – in ultra high relief – has been updated to reflect the year 2009; four stars have been added to represent the current 50 states; and the inscription IN GOD WE TRUST, which was not on the 1907 version, will be on the reverse (tails side) of the coin. Additionally, a small border was added for a more consistent edge. The 2009 coin will be made of 24–karat gold. The new 2009 Ultra High Relief Double Eagle Gold Coin will have the nominal denomination of $20.
The original coinage tools have been preserved and they were entrusted to the Royal Mint Engraving Team who, for the £5, the double-sovereign and the sovereigns of 2009, manufactured the coinage dies directly from Pistrucci's originals dating back to 1817.
