For decades, the leader in casino chip manufacturing was Paulson. Their logo is the iconic "Hat & Cane". This logo can be found on the clay mold of many of their chips or within the inlay. Paulson is now part of the larger Gaming Partners International, or GPI for short, which also owns B&G and Bud Jones.
