Barry Bonds' record-breaking 756th home run ball was auctioned Saturday for $752,467, well more than the estimates by memorabilia experts. Home run No. 755, the ball that tied the record, went for $186,750, according to Sotheby's/SCP Auctions. Both final prices included the winning bid plus a 20 percent buyer's fee, according to the auction houses handling the sale. Bonds broke Aaron's record of 755 with a shot into the right-center field seats on Aug. 7 off of Nationals pitcher Mike Bacsik. Matt Murphy, a 21-year-old student and construction supervisor from New York, emerged from a scuffle with the record-breaking ball after paying $100 for a $12 ticket during a layover on his way to Australia from his hometown.
