Let me be nice about this.

You said:
How about calling the chips unlicensed?

After prohibition ended in early 1930's, 95% of the joints had a state issued liquor license and were legal joints.
They added gambling which was "ILLEGAL" under state and Federal law.

That makes them operating "Illegally."

Do you collect Illegals?
If not, why do you care?
If you do collect them call them whatever you want.
We, the illegal chip collectors, will continue calling them what they are!
