There's collectors out there for almost anything. Here's what you do. Go to the bank and borrow $1000. Go to Caesars and buy one of the regular chips. Take it home and scan it. This will let you document the difference. Take it back to caesars and trade it for the error chip. Now they can't destroy it. It'll cost you $2 to put an ad on eBay to look for a buyer, or continue to shop for a buyer here and in the club magazine. The worst case is you can take the chip back to Caesars and get your $1000 back.
