First, I'm pleasantly surprised to see the R316 Douglas Park cards on this list, since I own a couple of them. But they really are just a stamp on the back on a regular card. How are they different from the T206 with the Howe McCormack stamp or the F stamp? If I stamp "Dave" on the back of a card, is it now on the rare back list? I think that I would only call it a "back" if it was printed on and not stamped (although how would you tell the difference sometimes?)
