My understanding, they would give you a token each month to the casino players. I'm guessing you had to be at a certain level of play to get the tokens (or it cost you X points).

There were 4 to the set.

There were a couple of sets of the tokens that have a "cash" value of $5 per token. I don't know if they could be used in the machines.

I'm sure that John Kallman can give you better details. Here a link to more of the tokens.
