Evansville police are collecting security video at locations affected by the passing of counterfeit $20 bills.
The transactions affect at least a dozen area businesses.
Pictures of the suspects have been released.
EPD says the phony money has most of the security features found on genuine bills, including watermarks and they pass tests from counterfeit detecting pens.
The difference is the textures and the watermark of Andrew Jackson are crudely drawn.
