The Philadelphia Transportation Company (PTC) used brass tokens manufactured by the Scoville Company for payment of a fare. The tokens were unique to the company and imprinted with identification. The transit tokens often had cutouts to differentiate them at a glance from other carriers. I have fond memories of my father sitting at the kitchen table on a Sunday night filling his token holder with tokens for the week. I always worried about him getting home if he lost a token; he never did!
