Capture both sides
The camera finds a four-sided card outline and waits for a sharp, stable view before capturing. A green highlight confirms capture. Flip when prompted. Uploads are checked too; no manual centering guides are required.
How pre-grading
works.
See how CardNomi checks your photos, reviews visible wear and builds a grade estimate using public grading guidance.
Scan a card ↗Check the evidence
The model checks each side for a physical card, correct orientation, focus, glare, sleeves, perspective and all four corners. Missing evidence produces retake guidance instead of a number.
Inspect four condition areas
Centering, corners, edges and surface each receive observations tied to the visible photos. Original photographs are the evidence. Background removal and optional display contrast do not repair the card or add detail.
Apply the selected grading lens
The analysis uses public company guidance and valid grade increments. Server checks reject impossible centering ratios, unsupported grade increments and top-grade results that conflict with the evidence.
Keep the context
Your report includes an estimate range, photo-check results and limitations. Eight magnified original corner crops support your own review. A catalog match supplies artwork and card details; it does not supply condition evidence.
Choose your submission lens.
These are independent companies. CardNomi is not affiliated with them, does not submit your card, and cannot issue their certifications.
Professional Sports Authenticator
Eye appeal, visible wear and overall condition.
Scale: Half grades below 9; no 9.5
Published Gem Mint 10 centering guidance: approximately 55/45 front and 75/25 reverse, or better.
Official grading standards ↗Technical Authentication & Grading
TCG-specific centering and visible defect detail.
Scale: 1–10; no 9.5
Published Gem Mint 10 centering guidance: approximately 55/45 front and 65/35 reverse, or better.
Official grading standards ↗Beckett Grading Services
Centering, corners, edges and surface.
Scale: 1–10 with half grades
Beckett assesses centering, corners, edges and surface. Gem Mint is 9.5; its special 10 designations are not awarded by CardNomi.
Official grading standards ↗CGC Cards
Visible condition with CGC scale distinctions.
Scale: Includes Mint+ 9.5
Published Gem Mint 10 centering guidance: approximately 55/45 front and 75/25 reverse, or better.
Official grading standards ↗Reviewed 2026-10-24-company-v2. Centering is only one part of condition; meeting a border tolerance does not guarantee a grade. CardNomi does not generate official subgrades, TAG DIG scores, Pristine or Black Label certifications.
What accuracy means here.
Sharper photos, explicit evidence checks and company-specific guidance can reduce avoidable errors. They do not establish a measured accuracy rate. CardNomi has not yet been calibrated against a representative collection of professionally graded cards.
What photos can show
Border balance, visible whitening, softened corners, edge chips, clear scratches, creases and other visible wear.
What photos can miss
Shallow dents, fine holo scratches, microscopic wear, restoration, trimming and counterfeit features. Lighting and compression can hide defects or make reflections resemble damage.
The displayed grade is an estimate, not an actual certified grade. Its range describes uncertainty and is not a statistical confidence interval. Centering percentages are visual approximations, not calibrated physical measurements.
For a valuable submission, use the photos as a screening tool and inspect the physical card under changing light. Only the chosen grading company can determine its final grade.
A few useful details.
Why can the same card receive different estimates?
Lighting, focus, camera angle and image compression change the visible evidence. AI assessments can vary too. Different companies also use different scales and professional judgment. Re-scanning does not certify a better result.
Does the AI use catalog pictures to grade my card?
No. Grading uses your saved original photos and optional angles. Catalog artwork identifies and illustrates the card in your library, while condition evidence comes from your copy.
What would establish a real accuracy rate?
A representative, permissioned dataset of paired front/back photos and verified professional outcomes, separated into development and held-out evaluation sets. Evaluation should measure grade error, estimate-range coverage, high-grade overestimation and retake behavior by company, card type and photo quality. Synthetic tests only verify software behavior.
