It is hard to tell from your view, but the Trek appears to be made with mostly Campy, and a bit nicer components.
I just don't consider the old Raleighs to be an extremely valuable bike, so I'd put maybe $200 on the Raleigh and $400 on the Trek. However, a lot of the value of the bike is just the buyer and seller coming together to a reasonable price agreement. What is it worth to you?
I like riding my bikes, rather than thinking of collectors value, but the Trek is in a bit better shape than the Raleigh. You could repaint the Raleigh, but then you would loose the "original" aspect of the bike, and it is easy to spend a lot on paint.
