Todd SchultzYou face several obstacles, unless you sift through the transactions to accurately classify them yourself. For one, there are alot of slabbed cards out there that still show a 1915 date for the sets, which is in error(Beckett even has some from 1917, also wrong). Next, M101-4 cards with Sporting News back will be labeled as such, so you can't call all m101-4's blank. Third, as you noted, some will be labeled with m101-5 or m101-4 even with a different ad back. Fourth, Globe Clothing has its own ACC designation (H-809), as do others (Standard biscuit and Weil come to mind).
Maybe you should list them as 1916 [ad name or blank back](m101-4)or(m101-5). Thus, maybe this could be a 1916 Globe Clothing (H-809) (m101-4) Joe Judge, to show the ACC name and the set with which it corresponds: (fuggit, the damn site won't let me upload, but you get the idea)
Edited to add: even the above idea has problems for the more than two dozen cards that are identical in m101-5 and m101-4 in a few sets.
