I've gone thru 6 bundles (600 notes) so far, mainly motivated by the awesome FWS 1000000 note found by johnh77 in Calgary on Sept 14. I'm using two branches of RBC in Montreal and running bundles back and forth one at a time (taking note of the numbers and plates for the SNDB of course). I was able to get within 177 notes (or two bundles) of FWT 1001001, which would be a binary, 2 digit radar, rotator, repeater...i.e. the most awesome note EVER!
But the bundles are not in sequence, serails totally unpredictable, and the tellers are getting frustrated with my clear abuse of the banking system. Apparently they seem to feel they do not exist solely to fulfil my personal need to find certain serial numbers on certain bank notes! Some of them are friendly and cooperative and others are downright hostile...like johnh77 said it helps if you know the head teller.
So far the coolest note I found is FWT 0995099 28 28 (a four digit repeater) probably UNC-63 since it went thru the automatic counter
If the notes come out of the automatic dispenser or an ATM the holograph is ruined, so I always ask for bundles which they keep in the back room, which means two tellers have to fetch them and this can take a while. Ideally, a bundle has a BOC wrapper around it and hologram scratches are minimal. The tellers will run new BOC bundles through their counter at least once unless you specifically ask them not to, in which case A) you will get a lecture about the bank accepting no responsibilty if there is a missing note, and B) you'll get a few UNC-65 gems without counting marks or scratches if you're lucky. I've never had a 'back-room' bundle or brick missing a note so I would definitely go this route.
I think its time to order a brick...single bundles rarely have anything good!
