Let me correct myself. We're talking about the molds used to make these chips - the "Nevada" and "Diecard" molds. Borland probably had the rights to use the molds, since he bought the molds from Bud Jones, who was the one who commissioned them originally. Bud Jones would have had the rights to use the molds, and undoubtedly when Bill Borland bought the molds he also bought the rights to use them.
The rights to the mold would have stayed with Bud Jones / Bill Borland, and not the casinos that used them. Borland wouldn't have needed permission from the casinos to make chips using that mold.
The inlay artwork, however, is a different matter. That would have been the casinos' property. But again, there was probably nobody around to object when Borland used it to make tribute chips.
