Check a certificate

Every slab we grade carries a certificate number on the back. Enter it here to see the card, its grade, and the four subgrades behind it.

On the back of every slab and in the QR code, like 0-N.

What you will see

The label as it appears on the slab, the card it belongs to, the overall grade and a breakdown of its subgrades: corners, edges, centering and surface. Also displayed will be a population report. Certificate images carry our watermark to prevent forgery. The card itself is never published publicly for privacy reasons.
