Exactly what I thought.
Most picked the highest graded card as their lowest graded card.
As you can see from the pics, the image is faded/blurry and has scuff marks on the front, and what the scan doesn't show, are the 2-3 indents and a slight indent/scratch as well.
The Silvera is super clear with no such marks on the surface, and only the top right corner brings it down, imo.
The Smalley, which I also pick as the top card is the lowest graded.
Other than that top border, which Scott noted, (which is hardly anything), is, imo, the best looking card with the sharpest corners. My only fault I find with it, is it could be slightly dirty or has off white borders, but it does look like it could be a cream front as well?
The Silvera and Shea were recently submitted raw to PSA according to the seller and the Smalley was submitted some time ago.
I have noticed these differences in grades before, but other than my Kuzava card, I haven't scratched my head like this in a long time.
Thanks for playing along.
