Jim,

Every hotel casino has a employee bank. It's where people who work in the hotel keep their bank.( the money they start each shift with)It's like lots of safe deposit boxes.It's also the place where you get change, cash in your tokes, get all the coin to fill the machines etc.Lots of different stuff shows up there.
The nice folks at the bank set stuff aside for me like silver strikes from different casinos, le chips, roulettes, ncv's etc.

Best regards,
Ralph
