I would'nt put so much credence on that auction being legitimate. I would'nt be the least bit surprised if the seller and the buyer are either the same person or friends with one another just trying to set the playing field for this chip. Dont always believe what you see on eBay, try to remember that at times there are improper tactics taking place on eBay. It's not that hard for anyone of you to create more than one eBay identification or have a friend boost your auction up. No offense to the seller, but the good and honest collectors here can also easily boycott buying from a seller who IMMEDIATELY places a chip like that online for a buy it now bid of 500.00 Happy collecting
