LEXINGTON, Ky. (AP) — Police in Lexington have issued a warning about counterfeit bills that have been passed multiple times in the area.

Police said in a statement that the department has taken more than a dozen reports of fake $100 bills in recent weeks. The statement says the bills are "prop money" and usually used in movies or TV commercials.

Authorities say the bills look very similar, but the fake ones are marked "for motion picture use only" and have a few differences including Ben Franklin's facial expression and the feel of the paper.

Police say people should use caution when receiving large bills and should verify that they are legal tender. Anyone who comes across counterfeit money should contact police.
