Do you have any idea how many different MC are on chips and dice?
I have 3 different hub chip ID's, and 5 different T's. Then there are all the other molds.
Take a look at TGT for MC.
There are a lot of dice records, but many do not have the actual hot stamp on them.
David will get the Taylor dice records on the Preserving Gaming History site one of these days.
I think the HCE dice records are already there. If not, they are in Mark's and my HCE book. They do have the hot stamps.
