If you are getting diamond graded by psa, check that they don't wrongly describe them as onyx. Maybe @jupityr can have them add 1/1 diamond to their database
I wouldn't use PSA personally. I've been so disappointed with their grades on cards that are virtually perfect it seriously makes me question their ethics. A card directly from a package into a sleeve should never be treated like a 30 year old frayed attic find, but that's how it goes I guess.
Considering sending some of the cards to be regraded by Beckett.
