The Seymour coded PS-FR JOCKEY chips are probably the most common of all the Antique chips. Mass produced in the early 1900s some clay but most are Bakelite. I have managed to find them in 10 colors. Seymour value is A $.50 and if you had to have some I can sell seconds for $10/100 RWB plus shipping. The chip in the Pic is a PINK/STRAWBERRY color Bakelite JOCKEY that Rog sent to me.
