Seller claims that he spent $100 on this chip.
It is possible, but only a very stupid person would spend $100 on a fantasy chip.
This is definitely not a chip that was ever used in a casino.
Doesn't claim that it is a "casino" chip.
Kind of implies that it could be redeemed in Vegas.
Not illegal, but very close.
