Powder coated 197 wheels

How much would I be able to sell 2nd hand freshly powder coated wheels in black or anthracite on here without centre caps?? Just testing too see how much they are worth?!?
 
I'd like to think that if I sold mine on their own I would get £400 with the tyres. Which when you think about it is a rip off as the refurb cost me £300 and the tyres about the same! But if I were to swap with someone for there original silver alloys, I think I'd want about £100 my way, plus they have to pay for them to be swapped over, unless we did it.
