Hello, Papadan, If you're bidding against re-sellers, you're in a good spot. They are only going to bid up to a certain point where they can buy it cheaply enough to flip it and make a few bucks, nothing wrong with that. The S-K box would be in the $15 to $20.00 range, depending on condition and contents. I would have a starting price of $75.00 for the socket set if I were to put it on ebay, The Auto-Kit set , if complete , and no owner's marks, $8.00 to $15.00. Don't forget your buyer's premium !!!! Good luck, Lou
