He turned the ticket over to his wife to check alongside some other lottery tickets, but the ticket ended up forgotten for a week.
"My wife found it in her pocketbook," Peace said. "I guess when she initially reached in to check the tickets she just missed that one."
The lost-and-found ticket matched all five white balls in the drawing, earning a $1 million prize.
"This is life-changing," he said. "How many people really win a million dollars?"
Peace said the win is exciting, but not necessarily that surprising.
"I've always had good luck," he said. "I always told people, 'I know I have the luck to win.'"
Peace said the money will go toward buying a new truck, bolstering his savings account and providing a good future for his grandchildren.
"We just can't put into words how happy we are and how appreciative we are," Peace said.
