A Kentucky man has won $AU140 million from a lottery ticket that was printed by mistake.

Lottery officials said Rob Anderson and his wife were winners of the largest jackpot in the state's history.

They've been buying tickets together for 12 years.

"We didn't hit it, that's not us," Rob Anderson said he told his wife after showing her the winning ticket the morning after the Dec. 26 drawing. "Something's not right!"

But they nearly didn't win the cash, as Mr Anderson revealed the winning ticket was a misprint that he decided to keep while buying stocking stuffers at a gas station. He wanted to buy $1 lottery tickets for three people, but the clerk goofed.

"The clerk ran the $3 Quick Pick but he put it all on one ticket, and I was like, doggone it, I needed three separate tickets," Anderson said.

The clerk asked him if he wanted to keep the ticket, which had three sets of random numbers.

"Yeah, I got a couple extra dollars," Anderson said, and he bought three more tickets to give as gifts.

When he arrived at home, he tossed the ticket on his dresser and didn't think about it until the Sunday morning after the drawing. When he remembered it, he checked the Powerball numbers and they matched one of the sets of numbers on the botched ticket.

Mr Anderson said he and his wife are grounded people.

"My wife taught me well, so to speak, to hang on to that dollar and see how far it gets you," he said. "We'll still clip coupons and still look for the clearance rack."

The couple said they haven't decided if they'll return to work.
