"The $4 gold patterns, or 'Stellas', are among our most popular lots," said Greg Rohan, the president of the auction house.
"Collectors are fascinated by the idea that the United States almost struck a $4 coin, going so far as to create patterns to show around the halls of Congress."
The four day event garnered a total of $23.9m.
