Edges

Edges refer to the four border sides of a trading card and their physical condition. When grading companies evaluate edges, they examine the thin strips along the top, bottom, left, and right of the card for any signs of wear, damage, or imperfection. Common edge flaws include whitening (where the card’s core material becomes visible along the edge), chipping, nicks, rough cuts from manufacturing, and peeling or separation of the card’s layers. Edges are inspected on both the front and back of the card, and graders often use magnification to detect minor flaws that aren’t immediately visible to the naked eye.

Edge whitening is the most prevalent edge-related issue that affects card grades, particularly on cards with dark-colored borders. When a card’s edge experiences even minor friction or impact, the thin layer of ink along the border can wear away, revealing the white cardboard core underneath. This whitening stands out dramatically on cards with black, blue, or dark borders, which is why certain TCG sets with dark border designs are notoriously difficult to grade highly. For example, many Magic: The Gathering sets with black borders and certain Pokemon full-art cards with dark edges are known to show whitening from even minimal handling, making high-grade copies of these cards particularly scarce and valuable.

For TCG collectors, protecting card edges starts the moment a card is pulled from a pack. Rough shuffling, storing cards loosely in boxes where they can shift and rub against each other, and even the act of inserting a card into a too-tight penny sleeve can all cause edge damage. When evaluating cards for grading submission, run your finger along each edge to feel for any roughness or irregularity, and examine the edges under magnification against a dark background to spot any whitening. Cards from sets with dark borders deserve extra scrutiny, as even a small spot of edge whitening can drop a sub-grade from a 10 to a 9.0 or lower. Proper storage in penny sleeves within top loaders, stored upright in boxes, is the best way to preserve edge quality over time.
