Historic 1oz gold coin goes for $4.6 million at auction

The so-called Brasher Doubloon, the country's first gold coin denominated in dollars, has been off the market since it was bought by a Chicago resident in 1979 for $430,000.

"The legendary Brasher Doubloon is one of the most important coins in American history because it's the first gold coin struck for the young United States and it's one of only a handful that exist," according to Todd Imhof, executive vice president of Heritage Auctions.
