There's no set value since these things are so rare. Good luck finding one. Most of them seem to be in Germany:

Anyway, given that there're probably about 200 in existence (collector sites I've seen never have c65s with serial numbers even near that) I think you're in for a tough search and even then expect to part with a lot of money, 'common' Amiga stuff goes for insane money these days so I can't imagine what a working, cased C65 would cost. The European Ebays are your best bet IMO - not the UK one though, we suck for C= stuff.
