True, but as is the case with notes cut smaller than their regular size, this sort of thing could be done outside of the printing company. I am not trying to imply that this is the case with your note, but what I am saying is that if a similar note surfaced, it is impossible to authenticate it as having happened during the printing process. What is to say that someone at the bank where you got the note, or perhaps Securicor/Brinks/etc, didn't do this somehow?
In my opinion, the note would be nothing more than an oddity, and would have no premium attached.
