Mark McGwire is known as “one of the most fearsome power hitters in baseball in the 1990s” and set a record with 70 home runs in one season back in 1998. This baseball was the one he used when he hit his 70th home run of the year, cementing him in the Baseball hall of fame. In January 1999 the ball went up for sale. It was purchased by a then-anonymous buyer at a record-breaking $3 million.
