Trying to research some old clay chips I recently purchased and hoping perhaps someone could shed some light on these.
The only information I have according to the seller is they were personal chips from around the 1940s-50s from the Biloxi, MS area.

I hope the photos come through ok. The one on the left is SAS, middle looks like ABS and right is CEP.

Thank you in advance for any help you can offer.

Sincerely,
Kari
