that landorus misprint is actually kind of cool! I think thats from the texture being pressed inversely through to the back. I have a SR Emboar just like it. If its too hard to look at it, I can always take it off your hands haha
im not a fan of PSA, but those lines on the back are factory issues, and not necessarily wear and such. Usually, if the card is otherwise clean, thats an average grade for them to give, i feel.
You’re right of course, but that’s more than your standard tiny white dot or print line… The card is obviously not damaged even if it looks like it’s been sanded, so I wouldn’t go as low as 6, though 9 is obviously pushing it.
