1804 dollar [SEP] Edmund Roberts' diplomatic mission
Later, in a letter dated December 2, 1834, Forsyth directed Moore to include "national emblems" (including an eagle and stars) on the exterior of the cases. In their book "The Fantastic 1804 Dollar", numismatic historians Eric P. Newman and Kenneth E. Bressett assert that a problem arose at the Mint as to how to interpret Forsyth's order. As his initial correspondence indicated that the sets were to include coins of every type then in use, Mint officials included both the silver dollar and gold eagle. The moratorium on silver dollar coinage had been lifted in 1831, but none had been coined since those issued in March 1804.
