[1880nonsports]

without it in hand - and no idea whether someone just replaced one stamp with another or the authenticity of any of the physical elements - I believe the 15 count packages (as opposed to boxes) were an outgrowth of the "Ask Dad" campaign of 1916. A possible reason why there are no notations relative to card insertion. I have CRS and there are a few members here with way more knowledge as to dates and packs.

I have actually sold all ten packs from a carton of "15's" containing exactly the pictured pack that I bought from a country store accumulation online. Couple had similar staining. I sold them all on eBay over a 20 year period. I sold the later ones with the caveat there was really NO CHANCE of pulling a card. I didn't know initially with certainty if they contained a card or not (I never opened a pack!) and left it up to the bidders imagination. One sells the sizzle and not the steak. The last two I sold was a few years ago - believe it or not they went for over 2000.00 (think I sold the second one to an under-bidder). Both were GAI graded.
I DO NOT believe I would pay more than 25.00 for that pack. It's distressed and not a "card carrying member" of the collect a pack club :-) Just one man's opinion. The go-with items like packs seem to be getting more attention. Despite my divestiture with regard to my collection - I see that as a good thing.

edited to add the admonition that 2000.00 was absurd. Fifty dollars about right as a "somewhat related" display.
