No trades or sales. These chips are still in use and I would have to charge full price. There is also a black $100 chip. These are "free play" chips and can be used on the blackjack tables (they pay off in real chips). If you ride a bus to Viejas they will credit you $10 free play each trip. It is a 30 minute trip to Viejas from San Diego and I also save $10 gas each trip. America, what a great place!
