There was a guy who ran charity casino nights throughout the the south including South Carolina, Georgia and Florida by the name of Charles J Freed. He used the cover of charities to run his operation giving a cut to the charity who hired him to run their casino night operation. These chips very well may have come from this operation and he may have been the one who ran the operation for the Jewish Federation in South Carolina. Florida at the time still felt that his operation was illegal to run since any type of gambling including those run for charities, He was raided and closed down In Florida at least twice I have been able to track down.
