70/30 Centering

See exactly what 70/30 centering looks like on a trading card and what grade PSA, BGS, CGC, and SGC will give it. One border is more than 2.3× the width of the other. The card visibly leans to one side.

What 70/30 centering means

A 70/30 ratio means one border is 70% of the combined border width while the opposite border is 30%. In a 3.0mm total border, that splits as 2.10mm vs 0.90mm.

One border is more than 2.3× the width of the other. The card visibly leans to one side.

Real-world example: Many vintage Topps baseball, T-206 tobacco era cards, and 1960s Topps football fall in this range.

What grade does 70/30 centering qualify for?

Each grading company applies different centering tolerances. Here's how 70/30 maps across the four major companies as of 2026.

Company	Grade	Verdict
PSA (front)	PSA 7	Front-centering tolerance for Near Mint 7
PSA (back)	PSA 10	Back tolerance still met
BGS	BGS 7 / 7.5	Significant sub-grade penalty
CGC	CGC 7.5	Drops below NM-MT 8 threshold
SGC	SGC 8	Visible miscut, sub-grade penalized
