I found a bag with mix of chips in it, including some that seem pretty old. I know some, and they are live AC chips (lucky me). Others are Vegas, and may/may not be live. Some are unknown to me....they say Tiber Entertainment on them, with a triangle. Anyone know if they are live, or worth something as collectibles.

Separate issue....what is the best way to clean chips of normal accumulation of dirt, oils etc.
