Card grading bias?

[glynparson]

The ganley is the one that can most be argued is under graded, however the type of wear is different in my opinion. I hate judging scans and i may feel different in person. The Johnson is more worn where as the Ganley is more bumped and folded corner wise. Again I am going from a scan and could feel different in person. PS I think that line may be the culprit. I honestly could be seeing it wrong but both bottom corners look to have those mild corner creases. i could be seeing things but thats what I saw to justify the grades. I would not argue if they were all the same either but one grade difference when not in hand and I think I may see something, I will usually figure Lummy got it right and I just feel the lower right is more rounded yet less worn than the johnson lower left. Its one of those grading sometimes different than eye appeal things. I honestly feel McBride and Clymer are clearly worse.
