Not being an attorney I do not know if I am correct on this but I would think that there is a difference between what we are doing and what the law says. In my opinion, we are not USING the chips. We are buying them and trading and keeping them in our collections. I would think using them would be in context of buying a gallon of milk with one or paying for your next oil change with some. We are using US Currency to buy these chips. We are not using the chips. In the context of trading or swapping, you might have a debate there but I still do not believe that would be anything to be concerned for.

I noticed the phrase in the law "for any monitary purpose" Could that be the key? We, as collectors, don't consider the chips as "Money" we consider them as collectable property. Their value while originally based on their face value are really valued for their sentimental or collectable value and the desirability of owning one. To me, at least, I do not consider my chips as having any value for any DEBTS outside the issuing casino. Their only value is in what someone is willing to buy or trade the chip from me for or for what I agree to sell or trade it for.
