Fair point, Pat but I would be curious what date do you think they printed them? 1912 or 1913? Not likely based off the players in the set and the look of the Coupon is just like the other 16 ATC brands. If they printed them in the 1909-11 time frame, then that would indicate they are the 17th American Lithographic ATC brand, but just printed in limited quantity and released regionally which may or may not been their full intent. I think the same reason they were printed/released in scarcity is the same reason Red Sun was printed/released in scarcity and Red Sun, we know was most likely released in early 1910 (produced in 1909/1910) with the intent to release a 2nd series at some point following that 1st series of 75 cards. With some Coupon cards having as few as 2-3 examples known, it is quite possible there could be a few yet discovered, and then perhaps proofs which might indicate more cards were going to be produced liked the Olberman T206 SL 8 proofs + Eddie Collins Proof. Why were those 9 cards not included in T206 set and why did it take 50 years for those cards to be known? Where do those fit into the T206 set? Does T206 represent 521, 524, or 530 cards to be complete? Why does the Old Mill T210 set released in 1909-10 have 114 cards? If Red Sun T211 which mirrors Old Mill T210 for 75 cards, and were to assume they were going to put 75 more cards in that 2nd series or would they just mirror the T210 set and put only 39 cards in that 2nd series ? All of these numbers are arbitrary for unknown reasons. Perhaps Coupon is the same ?! I believe Coupon was released in 1909-11 time frame and if Red Sun didn't do well and release a 2nd series in New Orleans, I believe Coupon could have been in a similar situation. New Orleans, regional brands perhaps didn't cut it against National brand cigarettes. More discovery hopefully to come!
