What would you do?(belt molding)

[57taskforce]

I've got a neighbor who's got a set of straight rust free doors and an excellent driver condition complete belt molding set from a '71 C/10. He said to make him an offer on the parts and we settled on $150 for the set of doors but I really know nothing about the value of the trim. Hopefully this doesn't get locked as I'm not looking for a value to sell something I'm only trying to figure a fair number to offer him. The moldings only really need polished and the black anodizing is faded but They are straight and extra-hole free. I'm not trying to violate the rules in any way.
Thanks guys and mods if you've got to lock it up I understand
