Those are some nice stamps IanAB.
My brother used to collect stamps at one time and old money bills. I had one of the last Canadian $1000 bills. The bank told me not to put it into my other bank account, it would be gone for ever. I didn't listen, it went into Mutula Funds. I think it had the Confenderation conference on the back, in Charlottetown PEI of 1867.
