Not to beat this one to death. But if you want to determine the value of an old bike part, blues 78, 1950's toaster, Thorens turntable, or Hummel figurine. Use a combination of the "completed items" search on ebay and a Google search for Internet dealers. The actual market where this stuff is listed for sale, sells, or does not sell. Is a much better place to determine value, then asking collectors who's opinions are too personal and completely biased. In this case there's actually a sealed set of Campy hubs on ebay right now. All David had to do was wait a week for his answer. Love it or hate it, ebay has made selling stuff you have no knowledge of almost fool proof. All you can do to screw it up is misspell, take lousy pictures, and list in the wrong area, and you will most likely still get a good price.
