Lethbridge police service say the print quality used at an establishment is similar enough to legitimate currency that a staff member didn’t spot the differences until after the male customer who handed it to them was long gone.

Police say while convincing, the bills had several notable flaws. Police say each bill shared the same serial number, lacked polymer material and holograms and had “Canada” misspelled as “Canad.” They were also marked “Not legal tender” and “Film production only.”

Now police in the southern Alberta city are trying to track that person down.
