I am far from being an expert but because the rest of the card looks mint, or very close to it, could the grade of 7 be fair even with that touch of paper loss on the back?
The 52 Topps PSA 9 Jackie is almost at a 1/2 million. (or is it already with the BP?) Real curious to see where this one ends as well.
