Kantinenmarken — canteen tokens — were issued by German military and paramilitary units to restrict purchasing to authorized personnel and prevent cash from circulating outside controlled facilities. T.B. likely designates a Truppen-Bataillon or similar unit designation garrisoned at Koblenz, a city that served as headquarters for the French occupation forces after 1918 but also housed significant German administrative and military infrastructure before and after that period. Zinc was the canteen issuer's metal of choice precisely because it held no intrinsic value worth hoarding.
