Is the security thread looks normal when viewed face-on? And when you look through with a light behind, what you see? On an authentic note, you must see the inscriptions "CAN 20" alternatively up and down along the strip. If you see a completely opaque thread, it's a phony bill.
The watermarks are quite difficult to imitate and on most faked notes (if not all), there is no watermark. And I cannot judge the quality of the cut because the scan doesn't show this part completely.
Don't forget that the raised dots are not by themselves a security feature, so their presence or absence cannot be taken as a proof of authenticity.
