I think Jim's right. There are hundreds of different nuanced variations. I think for most folks whether the card has some punch (in terms of unusualness and visual impact) is what affects monetary value. Leon's card clearly has that. For some people, part of a missing E does. For others it doesn't. Here are two of my favorites (not appearing anytime soon on BST). I think they have some punch. Others may disagree. It's no big deal; I collect what I like.
One of the consequences of the way most T206s were printed (vertical columns of the same card) is that there are lots of the "same" variation out there. By lots I mean a handful, at least. It's amazing how many cards seem like they could be one-offs, and several more are lurking out there somewhere.
