Found there are three levels of slot cards at Rocky Gap Casino in MD and Tom Dunn just sent in scans for the Gold card that is now on the ChipGuide along with the base Silver card. If anyone gets ahold of the Platinum level please send scans for the ChipGuide.

Here's a link to the scans on the ChipGuide
