Without knowing the type manufacture... and from what's seen in Victor's scan, the chips were a stock item by more than one distributor up to at least three years ago (and probably still a stock item). The chips in Victor's post (and the same exact color: orange; 3-Ring; Item #JH105 - John Huxley)) were used and cataloged as "Standard American non-value Wheel Checks for Roulette." Where exactly they were used as roulettes is unknown, of course.... but they certainly were used as Roulette chips in major casinos the world over.

We have a fun hobby with so much to learn.
