Big B small B $2 BBP

News: Registration is free here at the CPMF!

 I've wanted to ask this for quite awhile. Is the number known for when the big B changed to a small B in the 1986 $2 BBP prefix?

Any help would be appreciated.

I'm not aware of any such known changeover, but if there is interest, a list could be created, as done for several other subjects of interest.

I remember that prefix when it was released back in 1989-90.  I remember seeing a BBP with the big B somewhere in the low 3-million range, and a small B in the higher 3-million range.  

My two buck's worth is that the changeover is somewhere in the 3-Million range.

The CPMS Newsletter, Dec. 1998, had highest large B, BBP3332593, and lowest small B, BBP4734450.

Jonathan - your recollection appears to be spot on.  Did you keep records, or better still, the notes?  It would be great to reduce this gap.

I have been into serial numbers on Canadian banknotes for 22 years.  It has been so much an interest to me, it is my "fondest obsession".    In addition, I have an "eidetic" memory, which helps a lot.  

*I said "eidetic" after all those years of watching "Bill Nye The Science Guy" on PBS, way back when!

Anybody else have any questions to ask me?  

Keep up the good work!

I have 2 BBP large B, higher then that of 3332593

They are:

BBP 3444170 &
BBP 3444171

It would be interesting to see where the changeover actually takes place.
Anyone else with BBP's Large & Small B's ?

I'm creating a list and some corresponding threads to report new numbers.  Please post new finds there.

Thanks!
