warshawlawA medium o/c front card with otherwise nm-mt characteristics typically draws a near mint from them. Back centering isn't nearly as harshly hit.
The Matty is a mistake. Should not be better than vg-ex with the staining and miscut. Although in their defense a little, the front side looks pretty well centered.
The Wagner is nice but not near mint. I'd say ex+ to ex-mt would be reasonable, but since PSA doesn't have a tweener the 6 would be ok.
Here is how I measure the difference between 6-7-8: nice, damned nice, goddamned nice.
