Could the black line result in a details grade?
I recently bought this SLQ. It’s in a NGC slab and is graded VF 35. Everything lines up with online verify, although the listing doesn’t have a photo.
When I got my hands on it, I was surprised to see it has a black line running across the front, through the 9 to up near the Y in Liberty. It only stands out a certain angles. My second photo shows it better. I’m pretty sure it’s on the coin itself, not the plastic.
I’m wondering—could a marking like this result in a details grade? Essentially—did we get lucky this time, and a different grader might have decided details? Or is the line just part of the package that makes it an XF35?
