50/50 centering

A 50/50 card is perfect centering. It meets every grading company's top standard, including the 50/50 that BGS and CGC require for Pristine.

Drawn to scale. The left border takes 50% of the combined left and right borders.

How 50/50 grades

The best grade each company allows when 50/50 is the card's worse axis.

Company	On the front	On the back
PSA	PSA 10	PSA 10
BGS subgrade	10 Pristine	10 Pristine
CGC	CGC Pristine 10	CGC Gem Mint 10

BGS front subgrades here assume the other axis is well centered, since BGS judges both axes together. CGC doesn't publish back limits below a 9.

Measure your card

50/50 in millimeters

On a card whose left and right borders add up to 6 mm, 50/50 centering means a 3.0 mm border on one side and 3.0 mm on the other, a difference of 0.0 mm. That's invisible to the eye.
