"It's hard to shift "folding money" and "ten bob" notes these days! "
I had a couple of old £5 notes and was told only the Bank of England would change them......... I kept them in my wallet and one day I was visiting an office near by and so popped in. Worth the effort - Door keeper in long coat & top hat, directed into THE most oak clad and brass tellers room, £ notes taken, examined, ID checked and two new one handed over..... I felt RICH RICH
On the other hand I wasn't trying to bring in 10 suitcases of cash using a 1963 Driving Licence made out to "Ronnie Biggs"
