The SANDS CLUB in Emeryville CA. I have had all 4 chips for many years. I thought I sent them to the chip guide but I guess I forgot. The SANDS CLUB building is on the back. They are made like the brass core chips but the core is HARD plastic. On most of mine the gold lettering was worn. You found some nice ones. On the chip guide link you will see that they have the same Chinese writing and the word EXCELLENT as the clay chips. You always find cool things, good job.
