Yes, they are Pioneer Rex, Jackson, Calif. The same chip but with maroon and tan colors is from Pacheco Inn, Pacheco, Calif. They are obsolete. I also have the $1.00 from Pioneer Rex and have been told there is a .50 chip for both casinos. The Pacheco Inn also had a 10 cent, $1.00, 2 $5.00 chips, different colors, and a $25.00.
