I just created a new updated checklist for anyone saving Harrah's player number prefixes that matches the issue numbers in the latest 8th edition Slot Card Price Guide. The chart is an Excel spreadsheet and also includes entries for the Rincon, Harvey, Rio and Showboat Total Rewards cards. The blank form is available on my website at the top of the Harrah's slot card page. There's also a copy of the checklist that shows what prefixes I have vs what I need on the same page.
