~~~ R. Kellpie, who I used to trade dice for German chips explained to me in one of his letters that while inspecting his dice one evening with a black light he happened to pass the light over some Paulson chips and noticed the markings and, my response was that he should bring this to our attention in an article in our club magazine, which he did. We had no idea these markings were present back then and I had always wondered why nobody at Paulson informed us of this.
