I also have a bill like that, Lawson/Bouey, *MR series. I am using the Charlton Standard Catalogue, Canadian Government Paper Money, 21st Edition 2009. The check list is on page 285, and is listed as BC-46aA, with AA(Asterik note). There were 800,000 notes printed, estimated. According to the price list, BC-46aA, 1973, La-Bo, *AA aabove 5M, Yours being 8M, VG-$450.00, f-$600.00, VF-$1,000.00, EF-$1,700.00, AU-$2,500.00, Unc-$4,000.00. These are figures right out of the catalogue. I cannot photocopy because of copyright laws. I also cannot speak to the cut you describe. These are my interpretations to what I see on the bill and to what you have described. Hopefully, I am correct, if someone else could either correct me or support what I have found, that would be appreciated. Hopefully, you have a wonderful bill.
