The orange chip (PC) is Pioneer Club from Jackson, CA (1940s)

The $5 PI chip is Pacheco Inn from Pacheco, CA (1964)

I am going to guess that the other PI chip is also from the Pacheco Inn (same HHL mold) but I personally don't know the 40c denomination.

I am actually interested in these chips and I hope this info was of some help. Cheers.
