How to grade a trading card: the four areas to inspect.

Before you decide to submit a card, take a methodical look at its centering, corners, edges, and surface.

Professional grading companies use their own standards, so no checklist can promise a final grade. But collectors can make far better decisions by checking the same visible areas every time—and by looking at the back as carefully as the front.

1. Centering

Centering is the balance of the design’s borders from left to right and top to bottom. Look at it straight on, then compare border widths. A card can be clean in every other way yet lose appeal as centering becomes noticeably uneven.

2. Corners

Inspect all four corners under good light. Watch for softness, whitening, tiny dings, layering, and bends. Corners often hold up differently on the front and the back, so turn the card over.

3. Edges

Run your eyes along every edge without rubbing the card. Look for chipping, rough cuts, whitening, and small indentations. Dark-bordered cards often make edge wear easier to spot.

4. Surface

Tilt the card beneath indirect light. Surface issues can include scratches, print lines, stains, dents, residue, and creases. A sleeve can hide flaws, so make sure your photos are clear enough to reveal the card itself.
