What Is Grading?

Card grading is the process of having a trading card assessed by a grading company for condition and authenticity.

The card is usually examined for things like centering, corners, edges, and surface quality. It is then given a numeric grade, often on a 1 to 10 scale, and sealed inside a protective case commonly called a slab.

Graded cards can make it easier for collectors to understand a card's condition at a glance and compare copies more confidently.

At OnlySlabs, grading details are shown on each listing and ACE certificate information is included where available so buyers can verify the card more easily.
