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.
I've questioned psa grading as well on the 2018 topps mini x cryptocurrency especially 20 graded no 10s.
But. They are gold standard. My bgs 2018 cryptocurrency base cards hard to sell. Also maybe 2 bgs 10s. No black labels 40 graded
