Last weekend I was in an antique shop North East of Cincinnati. The owner had a sizable quantity of inlaid monogram chips in old USPC boxes. There were a few generic pokers chips mixed in and all were old USPC chips. There was this one blank, blue dot mold chip. Can one assume the chip is also made by USPC? Sort of guilty by association. White's in Cincinnati distributed these chips but they didn't make chips. I have not seen a dot mold without a hot stamp before.
