If you look at the very end of the Las Vegas Sands listings in the Slot Card Price Guide, at the white paper cards that are the "Sands Casino Guest Cards" with Green, Red and Blue printing... forget about the expiration dates, those appear to be wrong and should be ignored. What I just found was that there are actually two variations of the red printed guest card. On one variation the "g" in the word "rating" at the end of the last line in the paragraph is under the "a" in "cashing" above while in the other varation it's under the "h" in cashing. The fonts on the reverse are slightly different, most noticable in the "y" in "you" at the bottom
