Hi Paul,
The NEVADA DICE mold was used and made by Bud Jones after he split with Bill Christy. Later, the mold was bought from BJones by Bill Borland.
Both companies made chips using the mold to whomever wanted them, not just in Nevada. Besides counterfeiting Nevada chips with that mold and the DIECAR mold which he also bought from BJones, Borland DID make some legitimate chips for casinos and clubs.
