I'm going to be selling my irons but what is a fair price to ask, do you go by what they fetch on ebay or what you would get on golf bidder or a mixture of the two.
A fair price is whatever someone is willing to pay for them.
eBay etc is a good guide, any alterations you have made ( ie 1 inch longer/shorter ) will limit the appeal and reduce the prospective buyers
But if you get 2 6 FT 4 blokes after your long dunlops then you could have a bidding war, then anything could happen
