Does anyone have any chips with the hs JVM or JMV? Family members of a pal of mine used to work in an illegal place in Chicago and they are looking for this type of chip, based on the strong belief that it was used there. Don't know the mold or color -- all the info. they have is that the chips at this place were stamped with one of those two combinations of letters (most likely the JVM).

Chips would have been from around 1930 or so.

Thanks for any help you can provide,
