Charles Fey was the inventor of the trade check separator, which he used on his first Liberty Bell slot machines. The hole in the middle of the trade check allowed a detecting pin to distinguish the check from a solid nickel.

When his son, Edmund, returturned from Europe after World War I he joined his father and the compny was changed from Charles Fey & Company to Charles Fey & Son.

Tokens were issued in the 1920s and are original.
