Mark McGwire had been known throughout his career as a great home run hitter. In 1998, he changed the record books as the whole world watched. He, and Chicago Cub Sammy Sosa, brought back memories of the 1961 Mickey Mantle / Roger Maris home run race. McGwire eventually “won” by hitting the record breaking sixty-second homer seven days before Sosa. McGwire went around the bases eight more times before season’s end, leaving the new record at seventy. One of the most valuable collectibles is the ball from the home run autographed by Mcgwire himself. The value is $3,000,000.00.
