Centering is the balance of the borders: top/bottom & left/right. On perfectly-centered cards, top/bottom borders match as do the left/right borders. Centering is presented as a set of numbers & directions and often included with the grade. Perfectly-centered is "50/50 t/b" AND "50/50 l/r". As centering gets worse, one number increases and the other decreases. For example: 90/10 t/b is considered extremely off-center top to bottom. The numbers add up to 100 (50/50, 60/40, 90/10 ...).

Condition (Grade) Centering, corner wear, photo clarity, edges, creases, print flaws ... all combine to determine a card's condition or grade. Along with rarity/scarcity it is the major factor in a card's value.

Crease Defect usually caused by bending the card. Hard to see, or not, a crease lowers the card's grade (VG or lower) and greatly diminishes it's value.
