How to Check Pokémon Card Condition Before Grading

Updated October 9, 2026 · 6 min read

Graders judge four things: centering, corners, edges and surface. The weakest of the four tends to cap the grade. Here's how to check each one at home in about five minutes.

What you need

• A bright, diffuse light plus a single point light (a phone flashlight works) for raking across the surface.
• A loupe or your phone camera zoomed in.
• A clean, soft surface. Handle the card by the edges, ideally sleeved.

1. Centering

Compare the border widths left vs. right and top vs. bottom, on the front and the back. Express it as a ratio, e.g. 55/45. Back centering is usually judged more leniently than front. See our centering guide for how ratios map to grades.

2. Corners

Look at all eight corners (four front, four back) under magnification. You're looking for:

• Whitening — tiny white specks where the color layer has chipped. The back's dark blue border shows it most.
• Softness or rounding — a corner that isn't a crisp point.
• Dings or bends.

3. Edges

Run your eye along all four edges, front and back. Edge whitening and "chipping" on the back are the most common reasons a sharp-looking card lands at a 9 instead of a 10. Rough factory cuts count too.

4. Surface

Tilt the card under a single point light so it rakes across the surface. This reveals:

• Scratches, especially on holo and full-art foil.
• Print lines — faint straight lines from the printing process, common on some modern sets.
• Dents, indentations and creases — any crease is a major deduction.
• Fingerprints or residue — sometimes removable with a microfiber cloth, sometimes not.

Turning observations into a grade range

Don't settle on one number. Write down a realistic best case and worst case, then weight them. A card with perfect corners but one tiny back-edge chip is not a confident 10 — it's a "9, maybe 10." That range is exactly what the expected-value method needs.
