BALTIMORE — A rare 1804 silver dollar fetched almost $3.3 million dollars in what officials say is a record-breaking coin collection auction.

A five-part sale of the D. Brent Pogue coin collection that ended Friday netted a total of almost $106.7 million. The five auctions were held over the past two years by Stack’s Bowers Galleries of Santa Ana, Calif., in conjunction with Sotheby’s in Baltimore.

The final auction yielded about $21.4 million.
