Halifax Regional Police have received multiple reports of counterfeit $100 American bills being used at local businesses since August.
Most of the reports have been from the Dartmouth area.
Police say, if you suspect a bill is counterfeit, you don't have to accept it.
They say the best way to avoid becoming a victim is to check the security features on the bank notes.
Advanced security features on Canadian polymer bank notes can be found on the front and back of the bills:
- raised ink on the front
- large window containing metallic symbols and images
- maple leaf border around the large window
- frosted maple leaf window
American Currency has security features including:
- background colours and large, borderless portrait images
- unique paper made of cotton and linen with randomly distributed red and blue fibers
- off-centre portraits without a frame
- colour shifting ink on some notes
- security thread
- 3-D security ribbon on some notes
- serial numbers that correspond with a specific year
Anyone who suspects they've received a counterfeit bill, or believes someone tried to give them a fake bank note is asked to contact police at 902-490-5020.
