It would be pretty cool to see the first fresh $5 bills with printer letter I come to my region. I did, however, find one each of HCV and HCW pretty recently, and with lack of incoming tourists coming from outside Atlantic Canada due to the COVID-19 saga, it's possible that the newer $5 bills with the varnish coating may officially have arrived to Atlantic Canada now.
Or maybe the main branches have received a supply of the newly printed varnish coated $5s and they are now being distributed. I have a feeling it will be at least next spring before I finally see the $5s with printer letter I start appearing in my region. I suspect HCY will likely appear in Newfoundland before I see any of the IN* prefixes.
I did check the SNDB, and it appears there is a reporting of INB last I checked.
