So what would you do in this situation?
You have
literally asked the $64,000 question: four UNC French $25 notes that book for $16,000 apiece!
I might try the following tactics:
1) Say that your parent/grandparent was born on May 6, 1935 (the date of the notes) and this would make the perfect Christmas present for him/her. Or, your parents/grandparents were married on May 6, 1910 and celebrated their 25th wedding anniversary on May 6, 1935.
2) Going along the lines of Ottawa's idea, buy 10 ratty old 1935 English $10 notes on eBay for about $1,000 and offer the bank a trade (thus getting rid of 10 obsolete notes rather than 4
).
3) Threaten the bank manager saying that after x years as a customer with $y worth of assets with that bank, if they can't accommodate one small request on your part, you will take your business elsewhere and have your family do so as well.
4) Research the Bank of Canada's organizational chart, figure out who is the head of the area that will receive these notes, get really friendly with them REALLY FAST!!!
5) Send an imposter to this branch tomorrow posing as a Health Canada or CSIS rep., saying that a deranged old man is known to have brought some 1930s-era banknotes to a branch in the immediate area that were laced with Anthrax. If any of the bank's employees have information as to the whereabouts of these notes, they are required by law to turn them over for proper disposal, as they are biohazards.
6) If all options fail, I would definitely cry for more than a week! I might even go insane, send one final nasty e-mail to the Ombudsman of this bank, and then do as follows:
BTW...which bank was this? Not BMO I hope? If so, which branch of BMO?
