Police say it's a growing problem-- and now there's been yet another counterfeit money sighting in North Central Florida.

Earlier this week, fake 100 dollar bills were used at the Oaks Mall in Gainesville. Now police say a man tried to use a fake 20 in Alachua.

Fake money isn't necessarily easy to spot, but there are some things to look out for.

TV-20's Josh Rosenthal has the story. Watch the video to the right for more.
