If they are the Bally's/Paris $4 chips (numbered). They are not actually table chips. They are for sale by the cashiers as souvenirs. I was informed by two managers that they are not for use on the tables. The ones on the tables are not numbered and are not to be sold to cusatomers (under threat of dismissal apparently). Anyone should be able to go to a cashier and get one. I don't know if this is any help (I had a big fight with them at the time of the convention). If it is not a numbered chip, email me.
