Technical Help! Circle track dayton wheels

I need help trying to figure out what a fair price is for a set of 16'' Dayton wire wheels. They are complete with adaptors and knock offs. I have been told they are most likely from the late fifties. I also have been told that they are old sprint car or circle track wheels. The older fella that told me these things is well versed on older hot rod and circle tack parts, but was not sure what a fair price would be.They have right hand thread on one side and left on the other, early ford hubs on the front and 46- 48 on rear. THANKS FOR ANY INPUT.
