HHR mold was an old Langworthy mold. The mold now belongs to the Gamblers General Store, Next to the Union Plaza on Main St, LV. I am not sure of the HHL. Howard Herz book, Nevada Gaming Checks & Chips, lists all known molds and the Co that produced them. I will pick up a bunch of the PGI chips at the next show. I had about 12 of them and could not give them away.
