I finally managed to add the last of my doubles to my trading website. Everything available is now online including player# prefixes for Harrah's, and the Total Rewards cards from Harveys, Rio and Showboat. There's probably more than 7,000 different slot cards listed at this time with separate pages for just Montana and foreign cards, and another page of rarer cards. I have a few room keys listed as well even though I don't collect them. If you see anything you need let me know, everything is available for sale or trade for slot cards I need.

There's a Harrah's player# prefix checklist available on the Harrah's page and a list of the Montana barcode prefixes on the Montana page.

I'm specifically looking for Four Queens bus cards with different bus group#s if you have any for trade.
