How much is a factory set of Camaro 14x6 ralleys worth?

[MadMaxx]

Hey guys I have an original set of 14x6 rallies off a 69 camaro. They are all coded k-1-9 XG. All I can find out is that the XG means they are either off a 69 camaro with front disc brakes or a 68 camaro basic or ss with disc brakes? Please feel free to tell me what they are worth or even if I am correct on the codes. I also have the spare, which is like a anodized blue color. I want to sell them this weekend at a swap meet and am not sure how to price them. HELP!!
Thanks L G
