1964 topps question
 

I have a couple of cards that otherwise would be “grade worthy” except the scratch off on the back has been exposed. One clearly looks like it was intentionally removed back in the day, the other seems to have exposed just due to time...very faint

I think I once read that cards like this would always max out as “2”s due to “back damage”, regardless of the rest of the card. Seems harsh, but just curious if that is close to accurate. Just don’t want to waste limited grading bullets should I go that route

Appreciate any experiential advice

Sorry.. out this in the wrong section. Apologies...rookie mistake
