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. It was later revealed that the buyer was Todd McFarlane who has said that he spent his entire life savings on the ball. The sale was over 23 times the amount of any baseball before 1999. 

$3 million in savings is a lot of money to blow on just a ball, but Todd’s love of the game was obviously strong enough to overrule logic. On the flip side, if the ball has increased in value since then, it might turn out to be a wise investment. Only time will tell.
