HI FRED, JUST A SHORT RELATED STORY ... WHEN I WAS A CASINO FLOORPERSON AT CEASARS A.C. WE CAUGHT A PLAYER TRYTING TO RE-INTRODUCE ROULETTE CHIPS TO A HIGH LIMIT ROULETTE GAME .... HE HAD HARVESTED ABOUT 15 CHIPS FROM ANOTHER DAY AT $1 EACH AND TRIED TO USE THEM ON A $25 HIGH LIMIT TABLE SET UP FOR WHALES. HE WAS ARRESTED AND LATER NEVER PROSECTUED ... CLAIMING IGNORANCE ETC. THE CRIME OF RE-INTRODUCTION OF CHIPS TO ROULETTE GAMES AND POKER TOURNAMENTS ARE VERY REAL AND SCAMMERS HAVE CAUSED THESE PROBLEMS FOR COLLECTORS ... BE VERY CAREFUL!
