Searched a brick of $5 and found...

News: Registration is free here at the CPMF!

Notes that were shuffled so bad it was hard to tell that these were straight from the Bank of Canada as each band had it marked. The notes were also had heavy creases and bent corners.. I looked for errors and anything else that stoood out bu the notes were just shuffled.
The ranges were from HPZ27***** to HPZ21*****
I only searched the one brick (1,000 notes)
Lucky me I did catch a 2 digit radar in there - It was HPZ2221222

Thanks for the report.  This sounds consistent with what other brick hunters have said about CBN bricks, i.e., the mixing.  The printing floor at CBN must be a madhouse that they can't seem to keep sheets in order like at BAI.
