It would be best if you could come up with a price on your own. I can't help, since I may be interested in them and that biases my opinion. And to be honest, I'm not sure what they are worth. I'd have a better idea if they were for a 1970's car.
If you price them too high, they just won't sell, or people may make counter offers, so no big deal.
Are you sure they are NOS and not rechromed? That would be good information to know.
