J.B. has asked, regarding the BABN R/C $5s, "could the info be incorrect?
I do not see how it can be wrong as I have been able to put my hand to three documents all of which confirm it.
A memorandum from the chief of the currency division to the secretary of the Bank of Canada, dated 14 Jan. 1959, says in part,
"The Canadian Bank Note Company could begin numbering their $5.00 notes at number R/C 88001 where the British American Bank Note Company complete the order for $5.00 notes.
This will not be in multiples of 32,000 [plates were 32/on at the time] in either case but this will make very little difference because both companies will supply the right number of sheets to adjust."
BABN to Secretary, BoC, 21 Jan. 1959, reads in part, under "5.00 Notes", "Our last number on this denomination will be R/C 0088000.
BABN to Chief of the Currency Division, 29 Jan. 1959, lists notes on order to be delivered by the end of 1959, from which I extract
"$5 P/C 3424001 - R/C 0088000".
With this weight of document-based evidence, it would be difficult to make the case that the Charlton catalogue information regarding this changeover is wrong.
