is a rare 1941 dated guest coin from the Pfeiffer brewing co of Detroit, Michigan. The home of Johnny Fifer. This coin was used for the 1941 year to extend the privalages to the brewery tap room..not transferable. T is a number stamped on the back. This number was probably assigned to one person and only that person could use the token. T is a hole at the top probably so it could be put on a key chain. The brewery issued tokens for 1940 and 1942 with differnt symbols on the front. This is a tough one to find! and will be a great addition to any brewery or token collection! US buyer to pay $1.50 for postage, insurance optional.
