Esther,
I also picked up 37 other Caesars Palace Slot Cards on the same stroll around the casino. That was BY FAR the most cards I picked up in any one casino. And since they are now " not current" I have to be satisfied with that.
Palace Station yielded the most varieties--11 different cards. (unbelievably I forgot to pick up any chips from Palace Station)
I brought home over 200 cards to add to my assortment. I guess that I am now officially a slot card collector
Best Regards,
Murph
