1. I see that the Avalon and Sans Souci casinos had a 12 1/2 cent chip. Were these used at a 25 Cent Black Jack table to pay the player for a black jack or some other purpose?

2. About the 70 Cent Keno chip from the Plaza. What is the purpose of a chip for keno and why 70 Cents? Did any other casino have a 70 cent chip?

Thanks in advance for any information about this.
