The mold is a Die Swirl and is distributed by a small Co in Kearney, Mo called Mid West Games Supply. Today the chip is actually made at Atlantic Standard in Ma. The Horseshoe chip Tyrus is showing was made at the Burt Co in Ma pre 1988 before AS bought them out.
Thom's chip is an injected clay composit molded chip. Tyrus's chip is a clay compression molded chip.
The mold is not used much.
