Maurice Williams stopped at a 7-Eleven in Hyattsville, Maryland, one morning to pick up a $50 prize and left with far more than he expected. The 59-year-old school bus driver from Washington, D.C., bought another $5,000,000 LUXE scratch-off ticket after collecting the small payout, scanned it and discovered he had hit the game’s $5 million top prize.

Williams said he did not realize what he was holding until after he checked the ticket. “I didn’t notice I had a matching number at first, until I scanned it,” he said. The matching number was 59, the same number as his age. “It’s crazy because the matching number was 59 and I just turned 59 the other day,” he said.

The prize came from the $5,000,000 LUXE game, which has been offered only since February. Williams called his mother to help him calm down after he realized he had won, and he plans to buy her a house with the winnings. The 7-Eleven that sold the ticket will receive a $5,000 bonus, while two more top prizes remain in the game.

For Williams, the win turned an ordinary stop for a $50 pickup into a life-changing moment. For the lottery game, it leaves two more $5 million tickets still in play, a reminder that the biggest prizes can surface in the smallest errands.
