in 1834, the united states government intended to present a set of then-current us coins to four asian rulers the us had either made agreements with or else hoped to treat with. neither the silver dollar nor the eagle had been struck since 1804, but they were still considered current coins. putting the date of striking on the pieces would make them appear to be in violation of jefferson's prohibition which remained in force. mint director moore decided to strike 1804-dated dollars and eagles for the sets, and four 1804 eagles were struck. they differ from the pieces struck thirty years earlier, lacking a crosslet on the right side of the crossbar of the 4. two were presented, to the sultan of muscat and the king of siam, before the diplomat in charge of the expedition, edmund roberts, died of disease in macao, and his mission was abandoned. the remaining two sets were returned to the united states.
