The last home-run ball of Bonds' San Francisco Giants career was retrieved by Jameson Sutton, 24, of Boulder, Colo., at Coors Field in Denver on Sept. 5. Sutton kept the ball in a safety deposit box, wondering if it was Bonds' last home run, according to auction officials.
On March 13, Sutton hired SportsCards Plus Auctions to sell the ball. He reportedly hoped to use the money from the sale to help pay for his stepfather's cancer treatment, auction officials said.
An online auction for the ball opened March 31, and a buyer who chose to remain anonymous purchased the ball for $376,612 Saturday, officials said. Auction officials had anticipated up to a $1 million bid when the auction opened.
"I am happy with my decision to sell the 762 ball and wish the new owner the best," Sutton said. "I'm especially proud to help my family pay some of the medical costs due to my father's illness and thank SCP Auctions for all their help."
This isn't the first Bonds ball the auction company has encountered, officials said. The company sold ball No. 755 for $186,750 and ball No. 756 for $752,467 in 2007.
