Card Whitening, Edges and Corners: How Wear Affects Value
What causes whitening on trading card edges and corners, how to spot it, how much it lowers condition and grades, and how to prevent it with good handling.

Flip a card over and look at its edges. Those little white specks and lines along the dark border are whitening, the most common type of wear on trading cards. It's why so many "mint" cards from binders don't grade as well as their owners expect.
What whitening is
Most cards have a colored ink layer on top of paper stock. When an edge or corner is rubbed, chipped or bumped, the ink wears off and the lighter paper shows through as white. It's most visible on cards with dark backs, like Pokémon's blue back and Magic's brown back.
Where to look
- Back edges: the most common spot
- Corners: whitening plus rounding or "dings"
- Front edges: on dark or colored borders
- Full-art and borderless cards: edge wear is very visible
What causes it
- Shuffling and playing without sleeves
- Rubbing against other cards in boxes or binders
- Tight binder pockets or rubber bands
- Factory cutting, which sometimes leaves rough edges even on new cards
- Pack opening and handling with dry or dirty hands
How it affects condition and grade
- Tiny specks visible only up close: still Near Mint for raw sales, but can block a PSA 10
- Light whitening along an edge: often Lightly Played; limits grades to around 8–9
- Heavy whitening and rounded corners: Moderately to Heavily Played; low grades
See card condition guide and PSA grading scale.
How to check
Use a bright lamp and look at each edge of the back at an angle. A phone camera zoomed in or a jeweler's loupe helps. Check all four corners for rounding and soft spots.
How to prevent it
- Sleeve valuable cards right after opening
- Use toploaders or card savers for anything valuable
- Don't overfill binder pages or use rubber bands
- Store cards upright in boxes, not loose in piles

Can whitening be fixed?
No, and attempts like coloring edges with markers are considered alteration. Graders can detect them, and they reduce value.

Frequently asked questions
What is whitening on trading cards?
White marks along edges and corners where the colored ink layer has worn away, exposing the lighter card stock.
Does whitening lower a card's value?
Yes. Even small amounts can block top grades, and heavier whitening moves cards down to Lightly or Moderately Played.
Can new cards have whitening?
Yes. Factory cutting and pack handling can cause slight whitening on fresh cards.
Can I fix whitening on my cards?
No. Touching up edges is alteration, which graders reject and buyers dislike.
