The store will get a $100,000 bonus for selling the ticket to the fifth-largest lottery prize in U.S. history. An even larger Mega Millions jackpot will be up for grabs Friday night. Just who will collect the Powerball prize may never be known: Maryland is one of the states that allow winners to remain anonymous. The Powerball jackpot came only a day after nobody won the $970 million Mega Millions prize, the third-largest prize in U.S. history. Most winners opt for cash prizes, which for Mega Millions would be $716.3 million and $546.8 million for Wednesday's Powerball.
