I was reading about Mike online and I saw some articles stating that he made over 300 million over his boxing career but other sources like Forbes have stated that he's made closer to 680 million, meanwhile other articles go and say he made around 450 million. So I was just wondering if anyone knew the real amount he made and could back up their arguments by sharing contracts signed or purses revealed. I'm really curious since I'm such a big fan of Mike Tyson myself
