Most valuable private collection of US coins up for auction, could sell for $200M

A private collection of more than 650 rare American coins is set to be auctioned in a series of seven sales that could bring $200 million.

The D. Brent Pogue Collection will be sold by Sotheby's and Stack's Bowers Galleries beginning May 19.

It's considered the most valuable coin collection in private hands.

Sotheby's says the other six auctions will run through May 2017.

Most of the coins date from 1792 to the 1830s.

The May 19 sale includes an 1804 silver dollar considered to be the most famous coin in America. It could fetch $8 million to $10 million.

An 1822 Half Eagle $5 gold piece is also estimated to fetch $8 million to $10 million. It is one of three known to exist. The others are at the Smithsonian.
