HowieCards with back damage regardless of what's on the back must have the damage taken into account when assigning an official technical grade. If you have two identical card fronts, one clean back and one damaged back, they can't be graded the same. In these cases the technical grading is meaningless to how the card should be priced. The act of slabbing was more for authentication than it was for grading. Educated buyers of a cards like the Mack and Robinson know this. Casual buyers passing them over because of the low grade number don't get it.
