BALTIMORE (AP) _ A Sacagawea dollar accidentally made with a hole in its middle sold at auction Thursday for $8,625.

The so-called ``doughnut dollar'' was found in a roll of coins minted in Philadelphia and purchased by an unidentified Maryland man as a gift for his grandchildren in their Easter baskets. The coin was sold by Bowers and Merena Galleries of Wolfeboro, N.H., to another unidentified man.

The coin apparently was struck on a blank, or planchet, intended for the outer ring of a bimetallic coin being made at the Royal Canadian Mint in Winnipeg for use in Ghana.

``Somehow the silver-colored Ghana coin blank got mixed with a shipment of planchets intended for the U.S. golden dollars,'' said Q. David Bowers, president of Bowers and Merena Galleries.
