Regarding grading cards, I could be wrong about this. I think it’s very very very difficult for cards to receive quad 10’s by Beckett. To clarify this, I recognize that Beckett includes subgrades for centering, surface, corners, and edges. I have seen some PSA 10 cards that are not truly perfect. They have a minor issue with one of the four features mentioned above. That translates into 3 subgrades of 10 and 1 subgrade of 9.5 using the Beckett grading system. Out of all the Beckett 10 Pokemon cards I have seen on ebay, I have noticed that the edges are the feature which usually receives 9.5.
Two or three years ago, I saw a Japanese Pikachu card on ebay that received quad 10’s. Cards like this one are truly perfect. I wish I had downloaded that card and kept its image as a souvenir.
Just out of curiosity, does anyone have Beckett quad 10 Pokemon cards? If you do, what Pokemon are on those cards?
