Your prop chip was made for a show called 77 Sunset Strip, and for their a 1958 episode called "The Bouncing Chip".

The show was about two LA private detectives, and I watched "The Bouncing Chip" episode online, some years ago. Excellent episode.

The protagonist is hired to find out who is passing off counterfeit chips at a Las Vegas casino. I remember gambling scenes with close ups of the chips.

I remember a scene where the detective visits the Los Angeles headquarters of the chip manufacturer, and walks through their factory. Not filmed at the T. R. King offices unfortunately. The episode used to be online someplace, but I can not find it now. If you do you find it, it is worth watching
