The Cleveland Interurban (not Interboro) Railroad token is listed in Atwood's Catalog of transportation tokens as OH-175-AC. The 1970 edition of Atwood's states "The line which uses AC and AD (the token says City of Shaker Heights) operates PCC streetcars from Shaker Heights to downtown Cleveland. Except for the Shaker Heights line, which is still operating, the last streetcar in Cleveland operated on January 14, 1954." Google has a number of hits for "Cleveland Interurban Railroad".
