The major players as far as I can tell are Paul Endy & Sons, Dennis at TRKing, Jim Blanchard at ASM, as far as compression clay goes. Who am I missing as far as a major player?
Major players in casino chip production:
• Jim Blanchard at Burt Co., ASM, and
CPC.
(see below).
• Alphonse Burt at Portland Billiard Ball Co. (later renamed Burt Co.). Burt Co. also bought chip production assets from U.S. Playing Card Co. in the 1940s. After Burt's death in the mid-1980s, assets were diverted to two companies: Chipco International (John S, former Burt Co executive) and Atlantic Standard Molding (Jim Blanchard, former Burt Co. production manager). Upon forced government closure (tax fraud), Chipco assets were later sold to Palm Gaming international (and again later to ABC/BRPro) while Chipco ex-employees started new Game-On Chip Co. (later sold and renamed Chipco Inc.). ASM would later be sold to Red Ott, moved to Las Vegas, and renamed American Standard Molding. ASM assets were eventually purchased and moved back to Portland Maine under new ownership and company name Classic Poker Chips with former owner Jim Blanchard providing technical assistance.
CPC has since been sold and moved to Washington state under new ownership.
• George Davies and Paul Endy Sr. (plus his sons Paul Endy Jr. and Charles Endy) at T.R.King
• Bud Jones at Christy & Jones, and later at Bud Jones Co. starting in 1965 (acquired in 2000 by B&G). Initially resold clay chips made by Burt Co., later manufactured BJ plastic chips.
• Paul Endy Jr. at Paul-Son Dice and Card Co.
• Charles Endy at Top Hat & Cane Co.
• Paul Endy Jr. and Charles Endy at Paul-Son Gaming Supplies (later renamed to Paulson Gaming Inc.)
• Dennis O'Neill at T.R.King (son-in-law of original part-owner George Davies)
• Charles Endy and son Mike Endy at Blue Chip Co. 2002-2012, assets sold to GPI.
There may be a few others (chip/jeton pioneer at B&G, Stralka and Hispania owners, etc.), but that's about it:
Burt, Blanchard, Davies/O'Neill, and the four Endy's across several companies -- Paul Sr., Paul Jr, Charles, and Mike. Charles was likely the most heavily involved with clay chip production.
