Some plain mold and Dice Square records exist, they are split between Howard Herz and Bud Meyers.

Chain and USPC are in books published by Herz.
Howard prefers 2 chips for an ID. I've heard he's gone up to $10.
Bud Meyers will take cash but prefers a chip. Not sure how much, so far I have had something to trade.

H's are in a book and a CD. Email Mark Lighterman for it.
Both Allan Myers and I will do the large squares at no charge. I am thinking of putting them in a book but decided to wait and hopefully will upload the cards to Chequers as soon as the new owner takes over.

I strongly suggest you buy The Gaming Table. Most of us that reasearch old chips funnel the information to the publishers of TGT.

If you have a hub and its not in TGT, email me, I might have it. Between Steve Goodrich and I we have almost paid for the Mason Hub records.
Most of the NIS dealers handle TGT. Be sure to get the audit copy. You can also email Allan Myers direct for it.
