I have no idea how the set could have been so well documented, but I can tell you from experience that the relative scarcity of the cards in the E107 set varies widely. If you just look at the HOFers, there are MANY more E107 Waddel's, Plank's, and McGinnity's than there are Wagner's. Mathewson is even more difficult to find than Wagner. Other than mine, I can only name 3 others: Chris from Boston again, Keith Olberman again, and Larry Fritsch. I think that Scott B may know of another.
Scott is actually the best person to answer this question, since he has been trying to put the set together for a while.
By the way, I also think there is a range of scarcity within the N167 Set. The Ewing wasn't even known at the time of Lipset's Encyclopedia for example. There are only 2 - 4 examples known of this card.
