A dinged card is a damaged card. A ding can refer to indentations, scratches on the surface, or other types of damage. But the most common ding is associated with the corners. When a corner is bent, blunted, or otherwise damaged, it is called a “dinged corner”. Usually, this is caused when the card is mishandled. But sometimes, dinged corners result from cards simply shifting around in the pack. Dinged cards will typically receive a lower grade, and have a lower value on the secondary market.
