http://www.banknote.ws/COLLECTION/c...CANS0691.htmLooks VF to me but tough to tell from just the images (check for pinholes by placing it up on a pane of glass or in front of a light). Many of these notes have pinholes & there is a suspicious white spot in the centre).
C&C lists a problem-free VF note at $176.00
