I was told by one of the pit bosses that they are switching to the new picture chips and once the old style run out or wear out they are gone. It is interesting actually , because so many of the new picture chips have gone out to collectors and souvenir hunters that they have had to pull more of the old style back into circulation to meet the table requirements. In fact, on my last trip there, 03/07/01, they would not sell me any chips, and advised me that I was to play on the tables if I wanted to get chips.
