D/I 1954 $1 Test Note Laser Marked

News: Welcome to the Canadian Paper Money Forum.

I paid $1,750

It seems odd that the BoC would be using 1954 dated notes for tests done in October of 1975 if the Multicoloured series $1 was first issued on June 3 1974...

I saw these notes personally a little over a year ago while in London at the ONA Convention. Brian Bell was showing them to Graham Esler while he and I were having a chat.

Where all 20 notes still together at that time?

Probably not because I bought mine from Brian

Im surprised that charlton has not yet listed this info. in the current catalogue. Perhaps this should be added into the 24th ed.

I wouldn't expect these to get a separate listing in the catalogue any time soon. They were not circulating trial notes, nor were they internal test notes of any kind. They are simply regular notes that have been modified after the fact for a third-party organization to conduct some testing with.

I do not agree if a bank note is issued by the bank of Canada of modified by the bank it is of interest
to put it in the book.
to my knowledge it is the only example of work done by the bank of Canada on a note for a third party
If that is not a TEST ,I do not understand the meaning of the word TEST.
   

I could be wrong, but to me Test notes would be notes that would be put into actual circulation and not just treated and kept....I would also believe that there should be a substantial amount of notes entered into circulation and not just a handful...
The question I have is how are test notes actually tested unless they are in some way returned to the BOC to determine the results of the test...
Are all of the Test notes in the catalogue actually confirmed by the BOC ?

The other question that we have to ask to the bank of Canada is how many times the Bank
provided  modified notes to a third party?  and what is the purpose  of doing so if it is not for test purposes

L'autre question qu'il faut poser a la banque du Canada . Combien de fois la Banque a fourni des billets modifiés a une tierce partie? et quel en est le but si ce n'est que de faire des tests

I just took four photos of the laser marked note 1954 D/I 4001181 under a microscope

I'm coming in a bit late to this discussion.  Please see my article on this note in the Dec 2008 issue of the CPMS newsletter.  Another possibility to consider is that laser holes were indeed fine when the notes left the Bank of Canada, but the private company was applying a treatment to the note and the test of the effectiveness of the treatment was how many of the laser holes were obscured or filled in by the treatment.
