Campaign gti pirelli p's, what they worth

I have a set of 4 immaculate pirelli p's with genuine centre caps that im going to sell. The wheels were reconditioned a few years ago and are totally unmarked. The centre caps have a couple of light scratches but look very good otherwise. The p's aren't painted black either. They are fitted with 18555/14 firestone tyres with about 6mm tread each.
What do you guys think they are worth

Difficult one to call kev. On ebay lately even fully restod P-slots don't seem to be fetching the price they used to. You would think ?200 would be easy and they should go for more but I don't know if oyu'd struggle.

Unless you get a good offer in the forum here, perhaps put on ebay with a very high reserve just so you can gauge the interest. Atleast you can lower the reserve or at end of auction make offer through ebay still to the highest bidder.

I know the caps alone would make good money but i dont want to split them up
