Earlier this week, Ally Bank announced they'd hidden 100 "lucky pennies" worth $1,000 in 10 cities across the U.S., including Detroit.

WWMT reports that a Detroit man has found one of the $1,000 pennies.

Terry Williams said he was walking down the street when he saw something shiny. He decided to pick it up, and found out a few days later exactly how lucky the penny was.

Williams said he'd had the coin in his pocket for a few days before realizing it was one of the lucky pennies in Ally Bank's promotion.

According to the Detroit Free Press, Ally Bank launched the campaign to support the idea that every cent counts and to encourage Americans to look for opportunities to save.

The "lucky pennies" are hidden in plain sight in public places in Detroit, Chicago, New York, Los Angeles, Washington D.C., Miami, Denver, San Diego, Charlotte, and Austin.

The coins are slightly larger than an actual penny, with the Ally Financial logo on one side and "100,000 cents" on the other.
