newbie here, referred to your site from CCF, had no idea your site existed, looks great! I've collected paper money since the 70's, never too seriously.
Last week I picked up a brick of polymer fives from RBC in Montreal and was thrilled to find 2 radars, a 3 digit and a 4 digit. A little voice in my head told me to record the serial numbers before returning them to the bank the next day (teller was not happy, takes about ten minutes to return a brick). Unfortunately I failed to record the FP and RP numbers, which I see from this thread are useful to know, sorry! Since I kept 9 bills for my collection I have a few plate numbers.
The whole brick was HBP (plus I pulled a nice HBG7735777 FP35 RP35 a few days earlier). All of it Macklem/Poloz. Five notes in the brick were...what do you call them? position numbers? I thought they were replacement notes, what's the difference?
Anyway I'll gladly share my SN's with you but I can't find this SNDB of yours, where is it hidden?
