1911-D/D $20 Saint Gaudens RPM FS-501 (1911-D/D Saint Gaudens), RPM FS-501 PCGS MS65. This error, gem Saint-Gaudens double eagle is lustrous and well struck. Full details are seen on Libertys drapery, the Capitol building and its immediate area, and the eagles feathers especially at the top of the wings. The surfaces are original and clean with no individual distractions worthy of note. The luster is full and rich, as expected for a gem graded coin.

The D/D is called a repunched mintmark. They are known for most series of coinage, but are rare for Saint-Gaudens double eagles. Since mintmarks were entered separately, a slight misplacement of the punch caused the doubling.

Low relief Saint-Gaudens double eagle coins were first issued in 1907. They continued until 1933, when all gold production stopped. The low relief coins had Arabic numerals for the date instead of the Roman numerals seen on the previous two issues. In 1908, despite President Roosevelts preferences to the contrary, the motto IN GOD WE TRUST was added to the reverse.

The original High Relief Saint-Gaudens double eagles have long been considered Americas most beautiful coin; however, even the low relief coins that Charles Barber modified have had lasting beauty and appeal. The modern Gold American Eagle bullion program uses a modification of the low relief design, and it is exceedingly popular with investors as a replacement for the Union of South Africa Krugerrand.
