Condition & authenticity
How to tell your card's condition
Reviewed July 2026
The short answer
Card condition comes down to four things graders inspect: centering (how even the borders are), corners (sharp vs soft or rounded), edges (clean vs chipped or frayed), and surface (gloss, scratches, print defects, creases). A card that's strong on all four is Mint or Near-Mint; a weakness in any one drags the overall condition — and the value — down.
The four things graders inspect
Every grade is really a judgement on these four attributes together. Learn to look at them separately.
- ◆Centering: how even the border is on all four sides. A common benchmark is 60/40 or better front centering for high grades; badly off-centre cards are capped low.
- ◆Corners: examine under light and magnification — sharp points score high, soft or rounded corners drop the grade fast.
- ◆Edges: look for chipping, whitening, or fraying along all four edges.
- ◆Surface: check for scratches, print lines, indentations, gloss loss, and especially creases — a crease is a major defect.
What the grades roughly mean
Graders use a 1–10 scale. You don't need exact numbers to judge a card — the categories tell you most of what matters.
| Condition | Roughly means |
|---|---|
| Gem Mint / Mint | Essentially flawless — sharp corners, clean surface, near-perfect centering. |
| Near Mint | Very light wear visible only on close inspection; still very collectible. |
| Excellent / Very Good | Noticeable wear — soft corners, light edge or surface flaws. |
| Good / Poor | Heavy wear, creases, or damage; usually low value unless the card is scarce. |
How to inspect a card properly
Good lighting and magnification reveal flaws the naked eye misses.
- 1.Work under bright, even light — angle the card to catch surface scratches and gloss changes.
- 2.Use a loupe or magnifier to check corners and edges up close.
- 3.Hold the card up and eyeball the border symmetry for centering.
- 4.Handle by the edges only, and never on a surface that could scratch it.
Let the photo do the first pass
A photo-based read can estimate condition before you commit to grading or selling. Worth My Card reads centering, corners, edges, and surface from a photo and gives a condition read plus a hedged value range. Worth My Card gives an estimated value range from a card's attributes plus a condition and authenticity read — it's an educational guide, not a price database or a formal PSA/BGS/SGC grade.
Frequently asked
What are the four things that determine card condition?
Centering, corners, edges, and surface. Graders assess all four, and a weakness in any one lowers the overall condition and value of the card.
What does Near Mint mean for a card?
Near Mint means the card shows only very light wear that's hard to see without close inspection — sharp corners, clean surface, and good centering. It's a strong, collectible grade.
Does a single crease ruin a card's value?
A crease is a major surface defect and will cap a card at a low grade, sharply reducing value — though scarce or historic cards can still hold some value even creased.
