Thanks for the info! It would be interesting to see one sell at auction.
Hello Archey80,
You have got your wish! I have listed my BSW 0190139 with Geoffrey Bell Auctions, to finish on April 29. It is BCS certified VF-35 original. I am not aware of any ever coming to auction before and this should answer some of the many questions from over the years.
The listing can be seen at https://auctions.gbellauctions.com/Bank-of-Canada-20-2012-Scarce-BSW-Prefix_i56334402
