I can tell you for sure, there are no purchase orders or destruction orders remaining at the Four Queens for half dollar tokens.
Three years ago I found purchase orders and destruction orders for a $100 chip that is not listed in the CR. Only 53 remained unaccounted for. They were destroyed because of counterfiting. Three of these chips came into the cage and I starting looking for answers. This was the only purchase order and destruction order on the property or in the warehouse for chips purchased back to 1985. Nothing prior to 1985. Obsolete Foreign tokens and slugs are destroyed without listing each token by name. Anybody got an in at Gaming. They get a notice for all destructions.
