"Mini reams" and insert notes

News: Registration is free here at the CPMF!

I made some comments in response to a post on the $5 high\low boards (topic: AOP), and I think these comments are worth starting a new topic here.  Please tell me what you think.

The AOP's are not high but worth noting but this prefix has finally arrived here in New West.
Got these two from the local Beer store;

AOP6058170 fp 68 / bp 63
AOP6058169 fp 68 / bp 63

According to the BABN matrice this is from the Sub-matrice X-1/4. Does that fit in okay Huds?

PD

Since Huds is busy these days, I'll field the question in lieu of him.  Yes, your notes fit quite well.  I have likewise found:
6072405   85/90 X-3
6086427  96/84 X-2

The occurrence of these mini reams is quite regular throughout production of the new $5 notes.  I am in the middle of crunching some numbers and I intend to present my findings soon.  My findings support Hudson's theories that BABN $5 notes are printed in sheets of 40 notes, all with different FP/BP numbers, on banknote paper that is meant for 45 notes per sheet.  Instead of discarding the residual pieces, the printing company uses a "mini ream" to print 5 notes at a time on the leftover pieces.  Whenever the printer has enough of these residual pieces trimmed from the 40/on sheets, they print 120,000 notes before going back to printing reams of 40.

120,000 notes = 3 complete "normal" reams ( 3 x 40,000), and this is why BABN can continue to number notes consecutively without missing any in between.

Note to brick searchers: if you get bricks from the mini reams instead of normal 40/on sheets, and you find inserts in your bricks, I would speculate that the inserts MUST be SNRs, not sheet replacements.  How can they be sheet replacements if the notes they are replacing came from 5/on mini reams???

Can anybody confirm for me that the banknote paper used to make Canadian paper money comes from a foreign source?  This would explain why BABN has no leverage in getting paper with dimensions specific to their needs.

Thanks for reporting your finds, PD.

You make a great point about the replacements in Mini-Reams.

When I return to Canada I will look in my files and see if I have any Data that can Back up Mark's Theory. 

I have some support about the "mini-ream" theory.  But I found something interesting.

I got few bricks with AOV prefix (and I have a friend who do the same and share the infos he get).
Here the pattern (FPN/BPN) found:

Brick AOV6921*** (96/84): no inserts
Brick AOV6922*** (85/90): no inserts
Brick AOV6923*** (68/63): no inserts
Brick AOV6932*** (85/90): insert AOV5822521 (85/90)
Brick AOV6933*** (68/63): insert AOV5823521 (68/63)
Brick AOV6934*** (74/56): insert AOV5824521 (74/56)
Brick AOV6979*** (74/56): inserts AOV5824500-514, -117, -178-179

All the bricks fits in the mini-ream pattern. According to the pattern found in the insert notes, it seems that in the mini-reams, the inserts are put by narrow strips (one band of 5 notes), in each mini-ream of regular notes. So, we could have a third kind of replacement notes:  by strips.  But it raises the question: are the missing notes in any mini-ream are always replaced by picked-out notes from another mini-ream?  It needs more infos to support this theory.

Happy to see people working on this project.  It seems likely that when mini ream notes are getting replacements, the replacements would have to not be from full sheets.  I have found evidence of this in $20s, where they were mini reams, and the FP/BPs matched with the replacements, but the replacements were definitely not sheet replacements, based on how they were found.

"Strip Replacements" even in this case would have been impossible.  But perhaps they are possible (just not from my find)

Thanks Mark for answering the question for me. (I am sneaking a few minutes of Net at my parents place right now)
