Mold is called retangle 2 squares.

These chips were used in Tulelake Ca and Klamath Falls OR.

Both area's were at times under pressure from the local or State boys, so when the pressure was to much they moved their operation across the State line.

As you can see the Hot Stamp on the orange 25¢ chip is pretty weak, but readable.

Email for a better scan or if you have questions.

Thanks
