The refining of the information seems to point to the following:
What we calling "insert notes" are the notes/sheets that are put in their respective place to
replace spoiled notes/sheets.
This has been confirmed by the bank of Canada in that letter response to a member posing a question about this. (See Sudzee's website to see more about this)
http://gwfedora.tripod.com/id15.htmlHowever, it is important to understand that the QCIN's (Quality Control Inspection Notes) are still "inserted" into placement after analysis, but they are not there for the function of replacing spoiled notes/sheets. Most of the time these "QCIN's" are of the same family as descibed in earlier posts. We can conclude from this that the "QCIN's" are merely notes that have been taken out for analysis and inserted back into the brick. They do not replace any notes that are damaged.
However, the inserts that are "replacements" do exactly that -they replace notes that are absent/have been removed.
For example in any given section of notes where there is a changing point (000, 500 in $10s or 000, 250, 500, 750 in the recent $5s) you may find a group of notes like this:
ABC1234000 - typical base note for a brick
ABC1234222 - QCIN (This is an insert that does not have a replacement function)
ABC1234399 - QCIN (This is an insert that does not have a replacement function)
ABC1234444 - QCIN (This is an insert that does not have a replacement function)
AXZ9999988 - Replacement (This is an insert that DOES have a replacement function)
AXZ9999989 - Replacement (This is an insert that DOES have a replacement function)
ABC1234001, 002, 003 etc... - brick of notes continues.
I feel that it is very important that this issue be clarified like this. There are already many people working across Canada searching through notes and reporting information to the appropriate people to ensure utmost accuracy in the published number ranges. Additionally, this will ensure that the term "insert" is not tossed around inappropriately. Like I said, there are many people out there working very hard on this to ensure accuracy and through this careful contribution and collboration we can compile the information properly.
This is also where the significance of position numbers comes in. From the layout of a sheet, we can better determine startpoints and endpoints of replacement note ranges, with infomation based on what serial number ranges are found in a single sheet. Also, for matching up congruent finds from numerous bricks that have the exact same pattern of notes. For example if you had 4 bricks that came from the same sheet, each respective note would come from the same sheet. That is, each sheet in the grand stack of 1000 (or 500, or even 250) would have four positions in which the verticle stacks would make up the bricks/sections. Clear as mud right? Let me try that again:
ABC1234000
ABC1234222
AXY9994215
ABC1234001...
ABC1236000
ABC1236222
AXY9996215
ABC1236001...
These two "verticle stacks" would represent two separate coordinates of the full sheet. So when a sheet is inserted as a replacement, the replacement notes will make it into each one of the brick comprising stacks. Hopefully that makes better sense. But anyway, by figuring out more about the front and back position numbers, it may assist in the replacement research as well.
All from me for now,
Happy New year, please be safe everyone.
