BGS Centering Requirements for Every Subgrade

Updated October 18, 2026 · By the Binder AI Team

Beckett grades centering as its own subgrade. A BGS 9.5 centering subgrade needs 50/50 one way and 55/45 the other on the front, with 60/40 or better on the back. A Pristine 10 needs 50/50 all around on the front and 55/45 or better on the back. That makes BGS much stricter than PSA at the top, and it is why so many clean cards land at a 9 centering subgrade.

BGS centering subgrades

Beckett compares each side of the card separately. For the front, the 9.5 is the only level that asks for different numbers on the two axes. For every other level, the worse axis decides.

Beckett describes its scale as general guidelines rather than strict rules, and it awards half-point subgrades (8.5, 7.5 and so on) for cards that sit between two published levels without publishing separate numbers for them. Beckett's older grading scale page lists the Pristine 10 back as 60/40, while the current standards page says 55/45. We use the newer, stricter figure.

Why the 9.5 trips up so many cards

The 9.5 requires one front axis to be dead center. A card that measures 55/45 in both directions is a 9 centering subgrade, not a 9.5, even though 55/45 would pass for a PSA 10. Only a card that is 50/50 one way and no worse than 55/45 the other reaches 9.5. In practice that means you need to measure both axes carefully and know which one is the good one.

How the centering subgrade affects the overall grade

A BGS label shows four subgrades for centering, corners, edges and surface, plus an overall grade. The lowest subgrade weighs heavily on the overall grade, so a 9 on centering usually stops a card from reaching a 9.5 overall even when the other three subgrades are 9.5 or 10. A Black Label needs all four subgrades at Pristine 10, which includes the 50/50 front centering.

How to check your card against BGS limits

  1. Photograph the front and back straight down, out of the sleeve, on a plain contrasting surface.
  2. Upload both to the free card centering calculator. It measures every border to a fraction of a millimeter and applies the 9.5 rule for you.
  3. Look at both front axes. If neither is close to 50/50, expect a 9 centering subgrade at best and weigh up whether BGS is the right company. Our card grading companies guide compares them.

Frequently asked questions

What centering does a BGS 9.5 need?

50/50 one way and 55/45 the other on the front, and 60/40 or better on the back, per Beckett’s published standards.

What centering does a BGS Pristine 10 or Black Label need?

A Pristine 10 centering subgrade needs 50/50 all around on the front and 55/45 or better on the back. A Black Label needs Pristine 10 in all four subgrades, centering included.

Is BGS centering stricter than PSA?

At the top, yes. A 55/45 front can still get a PSA 10, but on BGS it tops out at a 9 centering subgrade unless one axis is 50/50. See our PSA 10 centering requirements to compare.

Does BGS grade back centering?

Yes. Each centering subgrade has a back limit, from 55/45 for a Pristine 10 and 60/40 for a 9.5 down to 95/5 for a 5. Below that Beckett publishes no meaningful back limit.
