I have just put a newly discovered chip on eBay for auction. It is a regular issue $500. chip from the closed Southern Belle casino in Riverbend, MS. The chip is purple with 8 grey and 4 white inserts and it has been cancelled "NO CASH VALUE". This chip is one of 19 that I know of to exist and unless he added it today it has not been in Gregs Cyberguide. I got a few of these chips from the guy who claims he was running the backhoe that was used to bury the chips after they were cancelled! You can see the chip by going to eBay - www.ebay.com and do a search for item number 12083053.
