Centering check

Enter the border ratios you measured and see whether they fit PSA’s front-centering limits for a 10 (55/45) or a 9 (60/40). Then check whether grading pays off after fees. Only the grading company decides the grade.

Front centering check
Left / Right Ratio52% / 48%
Top / Bottom Ratio51% / 49%

Within the PSA 10 front limit (55/45)

Front centering alone would not hold back a 10. Corners, edges, surface and the back count too.

Is grading worth it?

Enter the values you expect. Kiraset has no price data for graded cards yet, so nothing is filled in for you.

Empty = same as the raw value.

Enter the raw value and the expected graded value to see the result.

PSA lists 55/45 or better on the front and 75/25 or better on the back for a Gem Mint 10. A PSA 9 (Mint) allows 60/40 on the front and 90/10 on the back. Check psacard.com for the current standards.

Measure the border on each side of the front, for example on a flat scan. The ratio is the narrower border divided by the sum of both opposite borders: borders of 2 mm and 3 mm give 40/60. Do this for left/right and for top/bottom, then set both sliders.

No. BGS and CGC publish their own centering limits, which differ from PSA’s. The verdict here uses PSA limits only; the company buttons just change the slab preview.

No. It only compares front centering with the limits above. Corners, edges and surface count too, and only the grading company decides the grade.
