It is a UFC, but there are some that think it may be from Newport. Reason was during a sale from a estate of a Newport Police man, a box of chips was found in his possessions. It was said by him that the chips came from the Golden Horseshoe Club after a raid. There is a box of them also at a local Antique store claiming the same story. The box I saw was in red, not yellow but in all other ways it was the same chip.
Take what you will of this, since other than being in the possession of the police man, no other facts can be verified. I have two of those chips just for that reason.
