I was told by somene who was told by someone that these "S" chips were used in play at Shoney's Bar (closed - not sure how long ago) on Whiskey Row in Prescott.

Since gambling is illegal in bars in AZ... maybe they are - maybe they're not.

Any info on these would be appreciated incld'ing manufacturer/ approx. age if possible. Educated guesses are welcome - along with speculation/ logical assumptions and out-right lies...
(if nothing else, there's always entertainment value )
