T206 question: How does back damage affect grade and value?

[ethicsprof]

My good friend Steve Yawitz(glad to see you around,buddy) is quite correct in his analysis of things.
Unequivocally, the card is a 1.
I must say that the front is a real beaut and because the angelic portrait of
Johnson is my favorite T206 card, I think it would be quite a card for a collector to own for a decent price.
As far as its value as an investment, i would think of it as a Johnson portrait
sgc 10 and expect to receive the monies a Johnson sgc 10 would bring.
The back would make me think that little or no extra monies would apply here.

best,
