Rubber band marks
 

Sorry if this has been mentioned but what is the typical PSA grade deduction for faint rubber band marks? I have an extremely sharp '57 Mantle/Berra, 8-9 range, but was in a stack rubber banded together. You have to look at it on the side to tell.
Thank you,
Larry

It's treated like any other edge damage. The grade depends on the severity. If it's as faint as you say, it sounds like your card will grade a 7, but of course that's impossible to say without pictures.
