I never find anything casino related here in the Bible Belt. But yesterday while going to an estate sale trying to buy some jewelry I finally found a chip and something I have never seen before. This Langworthy "puck" has to be from the 1960's or 70's given the phone number and it is very heavy. The only thing I can think of for a use is a paperweight. The center is apparently a chip inlay. Has anyone ever seen one of these before? Any idea of value?
