50/50 Centering

See exactly what 50/50 centering looks like on a trading card and what grade PSA, BGS, CGC, and SGC will give it. Borders are visually identical on both sides. The card looks geometrically perfect to the naked eye.

What 50/50 centering means

A 50/50 ratio means one border is 50% of the combined border width while the opposite border is 50%. In a 3.0mm total border, that splits as 1.50mm vs 1.50mm.

Borders are visually identical on both sides. The card looks geometrically perfect to the naked eye.

Real-world example: Most prototype cards from the printer test sheet. Almost no graded population at this exact ratio.

What grade does 50/50 centering qualify for?

Each grading company applies different centering tolerances. Here's how 50/50 maps across the four major companies as of 2026.

Company	Grade	Verdict
PSA (front)	PSA 10	Perfect — qualifies for any grade
PSA (back)	PSA 10	Perfect — qualifies for any grade
BGS	BGS 10 Pristine	Required for a Black Label
CGC	CGC 10 Pristine	Centering ceiling for highest grade
SGC	SGC 10 Pristine	Optimal centering
