I also have two sets of mint in the box silver crome jonny lighting pull backs the afx and the tjet seires .These are also still in the orginal shipping cases ?Does any body know what the entire sets of gold and silver crome cars are worth as I am looking to sell these I dont need three sets of each.

The silver chrome sets were $36 new (including shipping). That was, what, five or six years ago. What kind of a return on investment are you looking for? I see sets of 12 pullbacks go for anywhere from $30 to $45 on recent internet auctions but I'm sure the chrome cars are more rare. That silly mascr.com site lists a set of 12 gold pullbacks for $79.95. They're the highest priced site for pullbacks by far.
