trust.

We grade it in-house

Every card is scanned front and back at 600 dpi and reviewed factor by factor by a human grader, with written notes for what we see.

It comes back slabbed

Your card returns encapsulated in a tamper-evident holder with its printed label — scan the QR on the slab and its private record opens online: the full-resolution scans, every subgrade, and the written report.

How we grade

Numbers, not opinions you can’t see

Grades are numbers only — no letter grades, no vague adjectives. Advanced service scores four core subgrades (centering, corners, edges, surface) that build the overall grade by strict, published rules — plus two presentation factors that live only in the online record.

The registry

Every card gets a record like this — and only you can open it

Each graded card’s private record carries the label exactly as printed on its slab, the full-resolution scans, every subgrade, and the grader’s written notes. There’s no public list — the non-guessable code on the slab (or its QR) is the only way in.
