Very strong front — excellent corners, edges and surface. The back carries minor whitening on the top corners and light left-to-right centering drift, which is what holds the overall to a Near Mint-Mint.

New — AI Grading
A full grade report before you pay a grader.
Two photos in, a grader’s verdict out: an overall grade with subgrades for corners, edges, surface and centering — every defect called out with its location, plus close-ups of each corner and edge.
- ✓Subgrades front and back — corners, edges, surface, centering.
- ✓Every defect located and described, with corner & edge close-ups to verify yourself.
- ✓Consistent by design: the same photos get the same grade, every time.
- ✓Graded cards save to your collection automatically — market value, price history and eBay sales attached.

Edges
Sharp on all four sides — no whitening visible.
Corners
All four corners are crisp and squared.
Color registration is dead-on; no print line shift.
Holo
Faint planking from age — common on Gym-era holos.
Verdict
Strong gem-mint candidate. Worth grading.

- ✓Needs both a front and a back photo, and issues a serial code like MGC-8S5A-KE5X.
- ✓You get a shareable image, a PDF, and a public verification page at /certificate/<code> with a QR code. Withdraw it whenever you want.
- ✓Sold as credit packs of 1, 3 or 10. It is not a professional grade or an appraisal — it documents what the AI saw in your photos on that date.

Community — collector Q&A
Ask the people who actually collect.
Centering, grading, prices, buying, selling and storage — asked and answered by collectors, on a board for every game and sport. Attach the card you just scanned and your question arrives with its measurements already on it.
- ✓A board for every game and sport — Pokémon, baseball, grading, centering, buying & selling and more. Polls too.
- ✓Attach a card — including the scan you just measured, so your centering ratios and grade estimate ride along with the question.
- ✓Best answers get accepted and answering earns reputation points and levels. Nothing picked up after a few hours gets a clearly labelled reply from @midpoint_bot.
- ✓Pseudonymous — usernames only, no real names or photos. Every published thread is mirrored read-only at /community, so reading is open on the web; asking, answering and voting need a free account in the iOS or Android app.
Is 48/52 centering safe for a PSA 10 on a modern holo?
48/52 is comfortably inside PSA 10 tolerance (55/45 front). Your back is 51/49, so centering is not what will cap this one — check the top-right corner instead.
Level 6 · 4,180 pts
No one had picked this up, so here is a starting point: PSA allows 55/45 front and 75/25 back for a 10. Your scan clears both. A collector answer will usually follow.
