Understanding the onyx grading scale

At Onyx Grading, we believe transparency is key. Explore our grading scale to understand how we assess and grade your cards, providing clarity and confidence in our process.

Transparency through subgrades

If you're unsure about grading, remember this: we provide subgrades at no extra cost. It's crucial to understand why a card received a specific grade, and our subgrades offer that transparency.  The QR code will provide the certification number as well as information about the card.

Our unique grading approach

Our grading scale uses a 1-10 point system with half-point increments. We distinguish between a Gem Mint 10 and a Perfect 10, the highest grade achievable. An algorithm determines the final grade based on subgrades, not a simple average.

From submission to return

Once your cards arrive at our facility, you'll receive an email notification. Another email will be sent upon completion of your order, letting you know your graded cards are on their way back.
