Just found a WHITE Jackpot Slot Club card from the President Casino at King's Landing in Tunica, MS that was not previously listed in the guides. Only red, silver and gold cards were ever listed from this casino and all are very rare. This may be a slightly different issue with different size text on the back and wider insert text on the front but I have no way of knowing what order these cards were issued so I'm adding the newly found white card in the same issue as the previously listed cards. We are still missing scans of the gold card if anyone has one and can submit scans to complete the listings for this casino on the ChipGuide.
