I came across this BCS Certified note for sale on the Colonial Acres website.
https://www.colonialacres.com/product-p/aug.dop.a53.htmThe description is given as:
BC-64b 2004 Bank of Canada $20 Jenkins-Carney Printed in 2008 Misplaced OSD, Partial Stamp, Holes BCS Certified VF25
There is something strange about this note particularly as it is certified by BCS and as it offered for sale as such on what I consider as a reputable dealer website.
Firstly I do not believe OSD terminology is the correct terminology because it was typically used for the OSD on the Bird Series Notes.
Secondly it talks about misplaced OSD which also typically refers to Bird Series Notes and the only journey notes where the hologram stripe has been misplaced is when the $5 and $20 notes have been printed on the wrong side.
Maybe they are referring to the missing intaglio on the hologram stripe as the misplaced OSD. But surely that cannot be an error as it can be very easily removed without affecting the underlying hologram.
