HI BOB. WOULD THEY BE A PERIOD OF TIME IN RELATION TO THESE EXPIRATION DATE PRINTED BY THE MANUFATURER; LIKE FOR ONLY SEVERAL MONTHS AND THEN IT WOULD STOP OR WOULD THEY BE 365 DAYS OF EXPIRATION DATES FOR THE ENTIRE YEAR OR YEAR AFTER YEAR???. THAT WOULD MAKE A LOT OF SLOT CARD TO COLLECT FROM THAT SAME CASINO IN ONLY ONE YEAR. MAYBE IT IS TO SOON FOR ME TO ASK THAT QUESTION BUT DO LMK WITH THANKS.
