Going rate for a Centurion Semi-Pro frame/fork
 

I'm going to be looking for one in the very near future, and wondering what a good price would be. It's a little hard to find comparable sales.

I got mine for $30, which was a steal. Paint is not that great, lots of chrome showing through. OTOH, I'm not sure I'd go much more than $100

I would say $75 in average good condition decent original paint and art work no dings dents bends. A choice colour and size in near perfect condtion with original headset maybe $125. I had a chance at one in OK condition with a slight dent on the top tube from the local bike coop for basically free and passed. A frame up build of nicer vintage bike is can be very costly and labor intensive I would say aim a little bit higher and spend some more time and money on finding something truely interesting special to build. It cost about the same to build up something just kinda good like this as it does something special.

I'll be building it up with modern components, which I already have. Any chance your local coop still has that frame?
