I don’t buy the grade without looking, trust me. I just understand what PSA has docked for historically and I’ve made decisions accordingly. I would never and have never bought a graded card on Ebay and complained to the buyer about its condition. The silvering issue is not new. One of the first gem mint graded cards I ever bought had silvering and this was over five years ago now. I understand the frustration if this is new to some people and I personally wouldn’t assign gem designations to cards with excessive silvering but it’s clear that PSA graders see it differently.
Don’t fall for the joker
Or hope for the spade
Always buy the card
Not only the given grade
