I was thinking of the one we used to go to in the early 60's. I found a photo online...I'm not sure where this one was.
I was trying to remember the name of these short-lived 'novelty' round corn chips. We were living in Houston in the early 60's and I remember these round corn chips coming out. I'm pretty sure they were from Frito-Lay and they were hyping the novelty of them being round and coin-like. That's I why I seem to recall them having a name like PESOS or CENTAVOS, but I see nothing online. I can literally picture myself at Chuck Wagon (or Chuc Wagun) eating a bag of them with my hot dog. I don't think they lasted long and maybe they were just testing them in that region.
