I have an exte extensive collection of illegal gambling matchbooks (as well as postcartds, dice, menus, etc.).

I don't know much about the Stock Club gambling in NYC. I know there are many dice out there (overpriced for the most part), but I don't know of any chips confidently attributed to it.

The Pluto chips/matchbooks are probably related to the French Lick Hotel, but again, other than city attribution, I have not heard alot about specific gambling. It might be that those beuatiful chips (of which I am sorry to say I have NONE) were used by the hotel for their patrons late night poker games. I know a couple of hotels (United States Hotel in Saratoga, NY, for instance) supplied their wealthy patrons with gambling supplies, without taking a cut. Perhaps the same thing was happening in French Lick. Someone needs to find the answers.
