The first 3 are 1915. Second 2 are 1914. Of the 5 pictured here I think the 4th shown, 1st 1914, has the least jersey/border blend. When buying raw from scans, I always choose the ones that have the most seamless blend between the border and the jersey to be sure. I also follow the 1914's much closer than the 1915's, but I would guess the print differences could be the result of more printing from the same plates on the cards that appear in 1914 and 1915. Also, the 1915's that were available by mail order instead of in the caramel box would definitely look cleaner.
