[old Chevy guy]

I had a guy ask if I had 16 inch 6 lug wheels for a C10. He actually wanted them for a camper he had that used that bolt pattern. I didn't think I had any but today I was looking at one of the parts trucks I have hidden somewhere else and it had a set of 4 on it. Not positive but they all seem to be in good shape. Wanted to call him back but dont want to give them away to cheap if they are hard to find or rare. So what do you all think they might be worth?
