I have a collection of London Underground platform tickets which I bought while driving around the system with my girlfriend. There are about 250 tickets with 16 missing from the 1965 stations. I'm clearing stuff out and was wondering whether people still collect these, and if so, can anyone give me an idea of their likely value. That would be most helpful, so thank you. And just out of interest, I and, 3 friends, held the Guinness World Record for the fastest transit of the system in 1979, and have the Guinness certificate to prove it.
