I've had these chips for years, but never noticed that they appear to be an unknown 8suit mold. I checked Robert's mold pages and didn't see one just like it either. I saw a "blank" chip in the same mold on ebay the other day and got to realizing that I had never seen another chip of this type. They are slightly larger and heavier than similar chips. These came from a long-gone Washington card room (sorry, no traders). Any others out there?
