Hi
Sorry, I was in a bit of a rush when I wrote that.
Okay here it goes:
1) CBN $20s we know are 45/on (45 per sheet).
2) The inserts of the 9.72 -9.99M range were found to be with the same FP and BP combination for 6000 consecutive notes. Meaning, 6000 notes per position, then multiplied 45 times. (= 270,000).
3) $20 inserts from CBN have so far been found as full sheet replacements.
This big chunk of notes 6000 high, in a 5x9 format is called a ream. The ream of notes for those inserts = 270,000 notes in total.
I hope this explaination makes better sense. I am drawing on the wisdom of many before me for this, plus my own research (which has confirmed what I have been told).
