Your old class ring or that set of silver missing a few pieces could make you money.
The Great American Treasure Hunt is set up this week in the Walnut Room of the Holiday Inn Joplin. Times are 9 a.m. to 6 p.m. today through Friday, then 9 a.m. to 4 p.m. on Saturday.
Old jewelry is considered a find by the treasure hunt buyers who paid a thousand dollars for a carat diamond.
While they're not appraisers they can determine values of gold and silver coins and jewelry.
Buyers say people may have things in their attic of value to collectors, like a flag from World War II and photos from a war photographer.
"The main thing is getting people out here to see what they have," says Janice Hall, Manager of the Great American Treasure Hunt. "The average person does not know the actual value of something - that's what we're here for. It's a free event and they get cash on the spot for their items, so it's really a good thing and it helps the economy here because they're going to spend that money right here in Joplin or wherever they live at."
