We already had two variations of the 2010 copyright gold level Harrah's Total Rewards Gold WSOP card listed in the guides but another variation was just reported. On the two already listed variations, one had no text over the mag stripe while the other had CODEGREEN. Both cards had the WSOP logo on the back right under the list of casino locations. The newly reported card is identical EXCEPT there is NO WSOP logo on the back.
Here's scans of the common front plus the two versions of the back with CODEGREEN but with and without the reverse logo.
