He said he first misread his chosen numbers on the lottery ticket, and only realized he won after looking at the numbers a second time.
The victor of the Mega Millions jackpot worth more than half-a-billion-dollars is a MI man who recently moved to New Jersey.
"It's not only life-changing money for me, but I want it to be life-changing money for others", he told reporters on Friday. "We're going to try to do some good things with that".More news: IAG Group Gets Stake of Norwegian Air Shuttle, Prepares Buyout Offer
"We're a humble family and we're going to keep our roots", Wahl said at a news conference, adding that they plan to give a lot to charity and help extended family members pay bills.
Richard Wahl says he bought an easy pick ticket for the $533 million jackpot in last month's drawing at a gas station. "I can tell you, it didn't sink in". Wahl's win was the fourth biggest in the game's history.
But he's also got some ideas for himself, like a vacation, rebuilding a 1960s Corvette and, hopefully retiring from his job. The store's owner, Ameer Krass, said he believes it's a store regular.

He bought the winning ticket at a Lukoil gas station in northern New Jersey and said the numbers were machine picked.
He said he went back to the Lukoil to fuel up after he won but before he came forward. He said he was getting on a flight Friday night, but wouldn't say where he was going. In particular, he is thinking of his mother, who lives on a reduced income, and the family of his wife, in Mexico.
The lump-sum option totaled $324.6 million, but after 24 percent in federal taxes and 8 percent for the state, Wahl is taking $220.7 million home, according to acting lottery executive director John White.More news: Explosions in Riyadh as air defences 'intercept Houthi rocket'
