jay behrensMy guess is that it got a 30 becuase of the glue stains on the back. Those marks on the back that look like grill marks are actually glue stains from albums. Having been an avid collector A&Gs, Kimballs and the like, I have seen a lrge number of cards with these 'grill' marks. I have a some N2 Indians that from the front look NM+, but have grill marks and this kept me submitting them to SGC.
