It really seems like there is NO guild lines. No blue book, NO way to tell, predict or plan for what any of these will sell for. I'm not even sure what that means.
But one thing is for sure, who ever won that action is more of the "I'm going to win it at any cost" type of person, then a collector making an informed decision because they liked, wanted or needed those parts! (Christ I hope my wife didn't win that!)
