I am not the grader, but I do see some differences between these two cards. The SGC 96 has a small printing fisheye in the upper right part of the blue. It also has a tiny white dot in the red to the right of Pedro Gonzalez's face. The SGC 96 also seems centered a bit lower than the SGC 98. Obviously these are incredibly minor "flaws", but for those interested in the difference between a 10 and 9, I am guessing those are the types of differences.
