SALEM, IL — The Salem Police Department is alerting the public to the circulation of counterfeit bills in the area.

According to police, several fake $20 and $100 bills have been passed at various locations in the area this month.

While many of the counterfeit bills have had multiple different serial numbers and were difficult to distinguish as fake, others have been more noticeable because of the texture of the paper their printed on, the color of the ink or the centering of the image.

If you suspect you’ve received a fake bill you’re encouraged to contact law enforcement.
