my own. Which is not much. My intention during the convention was to go to the Paris, MGM and Sands, in that order and find out what happened but too busy and never went to any. Will try by phone, if not next year!
Talking to people who actually played with them, and were around them, they claim that anything above $100 was taking out photographed and most were returned to the casino as nobody wanted to hold a $500 in a jeton/plaque at the time. Apparently has happened with all high denomination jetons and plaques.
And yes, I expect at some point they will start showing up but not untill after the casino stops accepting them. Hope that will be in a while.
BTW I do not see the photo in your post. Check please, would like to see them!!
