no advantage to grading 1/1's if you ask me...itll always be the highest graded, and I don't really see a demand on something...its not like its a vintage Mickey Mantle where the difference between a 9 and 9.5 is thousands of dollars
The front of the card some times might look perfect, but how does the back look? I have two cards that are 8.5 corners, but the front is mint, but on the back of one of the corners has a chip where the corner is peeling, cant see it till you look real close, but they see it. Still a sweet card at 9.0
