i honestly wouldn't consider most of the cards shown in this thread to be low grade. Eye of the beholder.
I put together my t206 set in low grade. My criteria was no missing pieces, not creases across the face. I actually think a T of E card looks more natural with even rounding on the corners, a mild surface crease, etc. I avoid cards with writing...back stamps on my T206s add to their story, though.
Here's an example of what I collect and probably mostly what you'll find in my T206 collection.
