A Calgary man who thought he won $100,000 in the lottery got a surprise recently after learning the real value of his win.

Giuseppe Dolcecore bought his ticket from Kaz Lotteties in Signal Hill and discovered the win when he returned to the same kiosk on March 14 to buy a ticket for the upcoming draw. 

"I scanned the ticket in the ticket checker, and I thought it said $100,000," he said in a press release. "But then I gave it to the clerk and he told me, 'It's not $100,000 — it's $1 million!"

Giuseppe says while his reaction to the news was understated, he had a difficult time convincing his wife that the win was real.

"I could believe it, I saw it with my own eyes," he said. "But my wife didn't believe me when I told her ... she said, "it must be a mistake, you make mistakes all the time."

Giuseppe says he plans to keep the windfall in the family so that he can help his kids.

Just four months ago, another Calgary man won the lottery.

Tom Crist walked away with $40 million and then pledged to give it all away in honour of his wife, Jan, who died of cancer in 2012.
