Pokemon Card Pre-Grading — Know Your PSA Tier Before You Pay $25 to Find Out
AI pre-grading for Pokemon cards in 90 seconds. Centering math that handles yellow borders natively, holo scratch detection on reverse-holo and full-art, and a deterministic rubric mapped to PSA's 1-10 ladder. The $0.99 sanity check before you commit to a $25 PSA submission.
Why Pokemon collectors over-submit (and lose the fee)
PSA is the dominant grader for Pokemon, and rightfully so — the population reports buyers actually read live on PSA's site, and a PSA 10 commands a clear resale premium. The downside is volume: PSA's bulk tier runs $15-25 per card with a 2-4 month queue, and that fee is non-refundable when a card you thought was Mint comes back a 7 because of edge whitening you missed under indoor lighting.
AuraGrade runs the same four-axis check PSA grades against — centering, corners, edges, surface — from two phone photos. If our centering ratios already flag the card as a 9-candidate, the math on PSA usually works. If the card pre-grades 7 or under, you saved the submission fee and shipping.
What our rubric scores on a Pokemon card
The rubric has 50+ deduction rules across four axes, derived from published PSA, BGS, and CGC grading standards. For a Pokemon card it specifically reads:
- Centering (CTR axis): left/right and top/bottom ratios from LAB-chroma analysis of the yellow border. 55/45 or tighter is top-tier; wider misalignment forces a qualifier or tier drop.
- Corners (COR axis): vision LLM identifies whitening, dings, and softness at each corner. Severity scaled per PSA's published corner-defect ladder.
- Edges (EDG axis): edge whitening density along the border perimeter. Yellow-bordered Pokemon cards hide edge wear less obviously than MTG black borders, but PSA still deducts heavily.
- Surface (SUR axis): scratches, print lines, indentations, holo-specific bleed. Holo-foil reflectance is suppressed before the surface pass so sheen isn't mistaken for hairlines.
Holo-specific defects: reverse holo, full art, secret rare
Reverse holo and full-art Pokemon cards show hairlines under angled light that base-set cards hide. The pipeline runs glare_detect → rectify → glare suppress (cv2.inpaint TELEA) before the surface-defect pass, so holo sheen doesn't get counted as a scratch. Holo patches are detected via HSV analysis and trigger an adjusted SUR threshold rather than a blanket downgrade.
Secret rare and rainbow rare cards carry the strictest surface tolerances because buyers pay the rainbow premium for flawless prints. Our SUR class flags rainbow-specific edge bleed and printing artifacts.
1st Edition, Shadowless, and Japanese print nuance
Print-era markers (1st Edition stamp, Shadowless framing, Japanese print) do not change the rubric. They're value modifiers you apply yourself to the predicted tier. Our job is to estimate the grade; the market applies the 1st Edition premium.
Japanese prints run slightly looser factory-centering tolerances than English prints. AuraGrade grades against PSA's published standard, not against print-run averages, so a Japanese card's predicted tier is directly comparable to its English counterpart.
From scan to PSA submission decision
The end-to-end loop is: upload front → drag the reference frame → upload back → drag the reference frame → receive a composite score with bbox evidence images for every deducted defect. Typical wall-clock time is 60-90 seconds including image upload.
Cards that pre-grade 9 or higher with a confident band are usually safe to submit. Cards that pre-grade 7 or lower rarely justify the PSA fee unless they carry a 1st Edition or print-era premium that survives the lower grade. Cards in the 8 band depend on your risk tolerance and the card's raw market value.
Common questions
- How much does it cost to pre-grade a Pokemon card?
- A single Pokemon card pre-grade is $0.99 USD, with packs starting at $4.99 for 6 scans. New accounts receive one free scan. The pre-grade itself takes about 30 seconds after both sides are uploaded.
- Does AuraGrade predict PSA grades for Pokemon cards?
- AuraGrade maps its 100-point composite to PSA's 1-10 ladder and lands within ±1 PSA tier of the eventual grade in roughly 70-85% of internal-test cases — meaning if we predict PSA 9, you most often receive PSA 8, 9, or 10. That's exactly the band where the $25 submission decision changes. Pokemon's PSA-dominant market is the primary calibration target; the band will refresh once the first 50 real PSA returns land.
- Does 1st Edition or Shadowless affect the predicted grade?
- No. The rubric grades condition (centering, corners, edges, surface) — print-era markers like 1st Edition stamp, Shadowless framing, or Japanese print are value modifiers you apply yourself to the predicted tier.
- Can AuraGrade detect holo scratches on reverse holo Pokemon cards?
- Yes. The server-side glare-suppression pass + HSV holo detection separate holo reflectance from actual surface defects, so reverse holo and full-art hairlines aren't double-counted.
- What about counterfeit Pokemon cards?
- AuraGrade does not authenticate cards or detect counterfeits. For high-value vintage or 1st Edition Base Set, use a dedicated authentication service before submitting to PSA.
