I figured as much, and they are listed in an auction as though they were real casino chips. At least they don't dissuade people of that view. Here is what the auction description is:

Lots of individual chips listed. . .. Funny, they don't show "EMC Grading's" opinion on the chips!!!! And no one can find "EMC Grading" on Google, at least I can't. Some call this type of thing a scam.

thanks again,
Robt.
