Mike,
The green on our chips IS on the Cal-Neva side, and it's just scribbles. We bought them on ebay, and I assumed that some kid had marked them up. (I've tried to clean them...no luck )

I agree, we should be able to trust our fellow club members in trades and transactions.... unfortunately, there are people who will always take advantage of others, and the club is not immune to that type of person.
