2003 Sacagawea "golden" dollar prototype - US Mint reverse, with "PEACE", brass prooflike

In 1999 the US Mint held a limited invitational design competition for the new Sacagawea "Golden" dollar coin. Although not initially invited, this concept designed by Daniel Carr was one of only two designs accepted from outside artists in the competition.

The obverse shows Sacagawea while on the Corps of Discovery (Lewis & Clark) expedition. At the time this coin was designed in 1998, nobody knew when the US Mint small "golden" dollars would first be issued. So the design was given a "2003" date in honor of the 200th anniversary of the Lewis & Clark expedition. The large "D" represents a "Denver" mint mark. A small "DC" (designer's initials) are visible at the lower right.

The reverse design was one of seven US Mint finalists for the reverse of the actual Sacagawea dollar coin. It features an Eagle soaring across the sun with 50 rays (symbolizing the 50 US states). At the time, there was also a proposal to include the word "Peace" on the reverse.

This design was sculpted in 3D by Daniel Carr, and the dies are made using a direct mechanical transfer from the 3D models.
To comply with US regulations, the reverse of the coin is marked "NON DOLLAR" rather than "ONE DOLLAR".
