The Hoosier Lotto ticket ended up being worth $3 million.
"My wife says it pays to be blind," Guffey said Thursday after he accepted his winnings at the Indiana State Fair in Indianapolis.
Guffey, who's from the northeastern Indiana town of Roanoke, said he didn't realize he'd used the wrong number combination until he had left the Huntington service station where he bought it.
He went back inside to buy a ticket with his usual numbers and that ticket won him $1,000 to go along with the jackpot.
Guffey said he has been playing the Hoosier Lotto since it started in 1989. He said he's won about $5,000 on various tickets over the years.
His wife, Janell, said they are going to pay off their house, take a cruise to Hawaii next year and set up a trust fund for their five children and 10 grandchildren.
"Christmas will be a lot nicer," she said.
