Saskatoon has been hit with a bunch of fake money this winter.
Saskatoon City Police are advising the public after a number of counterfeit bills were passed in the city.
Since the start of the year, a total of 72 fraudulent bills have been turned into Police, in the denominations of $5, $20, $50 and $100.
Police say the transparent strip on the fraudulent bills have all been altered.
Some bills include the transparent strip from a real $5 denomination.
The small numbers printed within the large transparent strip on a legitimate bank note will match the denomination of the bill.
Police are advising the public and businesses to check to make sure bank notes in their possession are legal tender.
