There are a couple of pig chips found in Dale Seyour's catalog, "Antique Gambling Chips". They are not "casino types" as far as I know, but are classic pig chips never the less.

1. PAPT , pg. 235, Pig Tail, engraved, with a value of "f", $8-$10, otherwise known as "Pig's Butt.

2. PAPZ, pg. 236, Pig Chef, machined and stamped with a value of "e", $6.00-$7.00, although I have never seen one offered and would give my eye teeth to have.
