In reply to Climbing Pieman:
Maybe the problem is that there is no such thing as a Scottish fiver!
There is a BOS fiver,
there is a RBS fiver,
there is a Clydesdale Bank fiver,
but there is no such thing as a Scottish fiver
BTW your own bank will almost certainly allow you to bank old fivers virtually for ever. My business still occasionally gets the old BoE £20 note and I can always bank it - any business that doesn't take old notes or even 'foreign' notes (eg Scottish or Northern Irish) are morons as you can always bank them.
