You are never 100% sure but I’m over 90% sure on this one. I believe the chips below are from the Dallas Petroleum Club. The club was formed in 1934. This is the year I believe the chips were delivered.

I have 4 chips available. $150 each for the yellow and $250 for the green

By the way, the DPC was what the Oil Barrons Club was based on (JR Ewing’s club)
