"Bud Jones stopped distributing the 2 molds in 1980 or 81 and sold the rights to the molds to our friend Borland in 1987 or 88.
All Nevada and Diecar molded chips after 1988 were made at Atlantic Standard and shipped to Bill Borland."

I now believe Borland bought the rights to the 2 molds in 1990-91.
