How Grading and Condition Affect a Card's Value

Updated June 2026 · 6 min read

Two copies of the same card can be worth $5 or $500. The difference is usually condition and grading — here's how it works.

The four things graders look at

Centering — how evenly the border frames the artwork.
Corners — sharp and undamaged vs soft or dinged.
Edges — clean vs chipped or whitened.
Surface — free of scratches, print lines and scuffs.

A small flaw in any of these can move a card down a full grade — and a grade can mean a big difference in value.

Raw vs graded

A raw (ungraded) card relies on the buyer trusting your description. A professionally graded card comes in a sealed slab with a certified grade, which buyers trust and pay more for.

The grading scale

Companies like PSA, BGS and CGC grade on a 1–10 scale. A 9 is excellent; a 10 (gem mint) can be worth many times a 9 for the same card.

Is grading worth it?

Grading costs money and time, so it makes sense mainly for cards whose value would jump enough to cover the fee and then some. For low-value cards, it usually isn't worth it. Check the raw value first to decide.

Frequently asked questions

Does condition really change value that much?

Yes. Centering, corners, edges and surface can move a card up or down a grade, and grades can multiply value — a gem mint copy can be worth many times a played one.
