重要なポイント
- PSA submission costs add up fast — pre-grading at home avoids paying to grade cards that will not return a profitable score.
- Centering, surface scratches, edge whitening, and corner sharpness are the four factors that move a card between PSA 8, 9, and 10.
- An eBay sold-comp lookup at the estimated grade tells you whether the submission breaks even before you ship.
Quick Answer
[Pokémon TCG Scanner](https://apps.apple.com/us/app/pokemon-tcg-card-value-scanner/id6765623646) is a free GradFlowLab iOS app that estimates a card's likely PSA grade from a photo and pulls eBay sold comps at that estimated grade. It is a pre-grading filter — not a replacement for PSA itself, but the cheapest way to avoid paying to grade a card that will not return a useful score.
Why Pre-Grade Before PSA
PSA's bulk tier is roughly $19 per card plus return shipping. For a card to be worth submitting:
- The estimated PSA grade at sold-comp prices must beat the raw card value
- The margin must cover both grading and shipping
- The submission must clear the wait window without the comp price moving against you
A card that looks "mint" to the eye but returns a PSA 7 instead of a 9 often loses more in resale than the grading fee. Pre-grading separates the cards worth submitting from the cards worth listing raw.
The PSA 1–10 Scale, Briefly
The grades that actually drive value:
| Grade | What it means |
|---|---|
| PSA 10 — Gem Mint | Perfect to the unaided eye. Centering tight, no surface scratches, sharp corners. |
| PSA 9 — Mint | Effectively flawless with one minor flaw allowed (e.g., slight off-center). |
| PSA 8 — Near Mint–Mint | One or two minor flaws. Sometimes profitable for modern, often not for vintage. |
| ≤ PSA 7 | Usually not worth grading on modern unless the card is scarce. |
Most pre-grading decisions live in the PSA 8 / 9 / 10 zone.
What the Scanner Checks
For each card:
- Centering — the four-border ratio analysis
- Surface — scratches, holo scratches, print lines, indentation
- Corners — whitening, soft corners, dings
- Edges — whitening, dents, fraying
You get a likely grade plus a confidence band and a short list of the specific issues that lowered it.
eBay Sold Comps in One Tap
The app pulls recent sold listings for the same card at the estimated grade so you can ask the real question: *at this grade, is the comp price higher than the raw price by enough to cover grading + shipping + time?*
If it is not, list the card raw and skip PSA. If it is, the submission is justified.
Pricing
Free tier covers scanning. Pro unlocks unlimited eBay comp lookups, historical comp charts, and bulk-batch pre-grading. See the in-app paywall for current pricing.
Try It
Get [Pokémon TCG Scanner on the App Store](https://apps.apple.com/us/app/pokemon-tcg-card-value-scanner/id6765623646). Run it on the next ten cards you were about to ship to PSA. If even one of them comes back below your assumed grade, the app has paid for itself before you printed a label.
よくある質問
Can a phone scan really estimate a PSA grade?
It can estimate, not certify. Surface scratches and centering are easy to see; subtle edge whitening and back damage are harder. Use the scanner to filter out cards that are clearly not 9 or 10 candidates — that is where most of the cost saving sits.
Why bother pre-grading at all?
PSA's bulk economy tier is roughly $19/card plus shipping at the time of writing. A card that returns a PSA 7 instead of a 9 often loses more in resale value than the grading cost. Pre-grading is risk management.
What does the eBay comp lookup do?
It pulls recent sold prices for the same card at the same grade so you can sanity-check whether submission makes financial sense before you mail anything.
