Hal LewisI don't consider your input to be a waste of anyone's time on this board. This whole thread has garned a lot of attention from curious onlookers, because after all we are dealing with baseball card HISTORY here.
If our collecting World is going to consider these Peck & Snyder cards to be the FIRST widely issued baseball cards... then we should know as much about them as possible... even if all we can do is discuss various THEORIES and how or why they may or may not be true.
I don't see this discussion as any different than the DOZENS of posts over the years about the M101-4 and M101-5 sets and all of their different backs and how those backs can be used to date the cards.
Likewise, I think T206 collectors can use the "Factory" on the back of the card to tell whether or not those cards were printed in 1909 or 1910 or 1911.
Yes, you and I are obviously lobbying for our respective cards ... and I'm sure everyone else would do the same ....
but in reality we are BOTH dealing with VERY SCARCE cards where one example is not really any more "common" than the other. Thus, regardless of which theory is true, neither card loses any value whatsoever.
It's not like mine is a "Ty Cobb" back while yours is a "Sweet Caporal" or anything like that! 
Here's the good news: I am never going to sell my card anyway, so there is never going to be some big auction house writing up a bunch of "puffery" about how my card is "so much better" than all the rest because it is older, blah, blah, blah. As you pointed out, nobody could ever really prove this anyway.
I would love my little card even if it had the 126 Nassau back ... and I will never hesitate to purchase one that has the 126 Nassau back if I see one for sale... assuming the price is right!
