I do agree with T.C. of Calgary that come Mar 17th, we will see (CBN) EJA $100 notes issued to the public. Remember as BOC will quickly pull all existing (Bird) $100 out of circulation, a large amount of Joruney $100 would have been printed to replace them. IMO the EJE given as a gift at the kick off launch in Vancouver could probably have pulled from some bundles of inserts for EJA... notes, or it may just be a regular note!?
Also IMO, there will probably be between 20,000-30,000 sets of Lasting Impression issued in BJY, with Bird BJY by BABN and Journey BJY by CBN. And if CBN already have the plates for Journey EJA-EJE...etc, there is no problem for them to print 20,000-30,000 BJY prefix notes before going back to EJ... prefixes.
Yes T.C. has a very interesting question on the signature combinations. Will Birds BJY be in Knight & Dodge or Jenkins & Dodge? Hard for me to guess. Time will tell.
