Jim ThierfelderI'll add that I am no expert either (barely a novice) but there is also a difference in the space above the grandstands. The SGC has a sliver of yellow between it and the border, the PSA does not.
I too would be interested in know about this variation.
Edited to add that after looking closer it is just a registration issue as the yellow is a bit out of allignment compared to the blue.
