AI card grading
Honest AI card grading for the cards you actually want to understand.
Upload front and back photos, let Mintventory inspect the quality signals that collectors care about, and get a conservative 1 to 10 score even before the card is added to your inventory. It is built to feel like a real grading experience for collectors, but stays clear that it is an internal Mintventory estimate, not an official slab.
Front + back
Upload both sides so the grading sees the whole card, not just a good angle.
PSA-style checks
Centering, whitening, corners, scratches, dents, and surface wear all matter.
Honest scoring
The output is intentionally conservative so Mintventory grading stays trustworthy.
Saved to inventory
The score becomes part of the card info and stays visible on your collector page.

Photo tips
The better the photo, the fairer the card score.
Mintventory grading is deliberately conservative. If the image is blurry, cropped, angled, or covered by glare, the experience should tell you that up front instead of pretending the result is precise.
Use soft daylight or even studio lighting. Hard flash can hide scratches and whitening.
Lay the card flat and keep it centered in frame so the edges are easy to judge.
Upload both the front and back. Surface wear, whitening, and corners often differ side to side.
Remove sleeves, top loaders, and reflections when possible so the image stays readable.
FAQ
Common questions about AI card grading.
This page is designed to answer the questions collectors usually search before uploading card photos for a grading estimate.
What does Mintventory grading check?
Mintventory grading looks at the visible signs collectors care about most: centering, corners, edges, whitening, surface scratches, print lines, dents, and other obvious wear on both the front and the back of the card.
Is Mintventory grading an official PSA grade?
No. Mintventory grading is a private, conservative internal estimate designed to help collectors understand card quality before they decide whether to submit a card for official grading.
What photos should I upload for the best result?
Upload clear front and back photos in soft, even light. Keep the card flat, centered, and avoid hard flash or heavy glare so the condition signals stay visible.
Where does the score appear after I save it?
The Mintventory grading score is saved on the inventory item itself, then shown again in the collector experience so you can review the score without re-uploading the photos.
Ready to grade?
Add a card, open it in inventory, and let Mintventory grading score it.
The score is designed to live where collectors actually need it: inside the card record, on the collector page, and next to the rest of the inventory context.
