try the classic and vintage forum. What derailleurs? What kind of shape? Unless its got high end componets i.e. Campy Nuevo Record brakes, levers, derailleurs and shifters, and is in excellant shape, its not going to really be a collectors item. Average shape, mix of french componets, i'd put it around $150. My 2 cents, and not a very informed opinion without pics and componets listed.
