I found some interesting information on the club in the 1959 autobiography of Roger Touhy. Touhy was a known bootlegger in the Chicago area and a competitor to Al Capone. This information reliably places the Dells Club in the Chicago area ca 1933. These chips have often been attributed to Evansville, Indiana. The Indiana "Dells Club" appears to have been active much later (ca 1952). They may have "inherited" the chips through common ties with the Chicago outfit.

From an earlier post in the archives:
"The brown and green chips were made by USPC in Cincy in 1928. The order was shipped to E.T. Fians in Chicago."

The Dells was " ...A Capone syndicate night club and gambling joint near Morton Grove" (Morton Grove is a mile or so north of the Chicago border) and "...a widely known roadhouse where such headliners as Joe E. Lewis had played." (Joe E. Lewis was a comedian who had his throat slashed by "Machine Gun" Jack McGurn in 1927) "The gambling rooms, presumably as crooked as all other Capone casinos, were on second floor."

Sam Hare was part owner of The Dells. According to John Landesco in his 1929 report, "Organized Crime in Chicago", Hare was "a roadhouse and gambling joint owner" and had been part of the James Colosimo trust ca 1912.

The Dells Club was the site of the well publicized fake kidnapping of Jake "the barber" Factor in 1933. Factor was a millionaire swindler, and the half brother of Max Factor, the cosmetics tycoon. Touhy spent 25 years in prison for the crime before a judge ruled that the kidnaping was faked. Factor had staged the kidnapping to escape extradition to England for a multi-million dollar swindle. It's likely that the Capone organization had a hand in it.

Two of managers of The Dells were implicated in the Factor kidnaping. One of them, Joe Silvers, turned up missing in 1933 (probably because he knew too much about Factor case). The other manager was named Silversmith.

Touhy was gunned down only 25 days after he was pardoned in 1959.
