In the early '80s I had several bikes with sew-up wheels, and I converted all of them over to 700-C. I still have all the old sew-up rims. Are they of any value at all; and if so, how would you go about selling them? Thanks!

New vintage of some models have serious value. Your average
40 year old technology was unremarkable and hasn't improved
in popularity over time.

Anything used will be hard to give away (unless it's built
on some desirable hub).

I've even seen some of them on which the anodizing went all the way around and the brake shoes had to wear it off to get decent braking.
