Raw Card Dealer Grading Descriptions

[Tere1071]

I recently purchased 10 1953 Bowmans as upgrades for my set. The cards were mostly described as being in Nr-MT to Nr-MT plus condition with the front sides only displayed. When I received the cards, several had wax/gum residue stains on the reverse. I'm never going to submit these to be slabbed, but I feel that the descriptions provided by the seller were "optimistic" due to the stains on the reverse side.

Admittedly I erred in only looking at the fronts of the cards and not asking the seller for additional images or checking to see if any had stains on the reverse side. For me, cards that have wax residue on the reverse aren't Nr-Mt or better. The seller has a liberal return policy so there's no problem, but am I judging these cards too harshly as this is a common occurrence in the 53 Bowman Color set?
