A Genesee County man says his heart started pounding when he thought he'd won $50,000 on a Michigan Lottery scratch-off ticket. Then, when he took a closer look, his heart started beating uncontrollably once again. That's because he'd misread the ticket. Instead of winning $50,000, he'd actually won the game's top prize of $500,000. The 51-year-old winner said he initially couldn't believe he'd won $50,000, but the real surprise came later that day.
