Section 1: What Does an 8.5 Centering Grade Mean?

Understanding the Score

If you've ever asked, "why did my card get an 8.5 for centering?" you're not alone. The 8.5 grade signals that your card's centering is slightly off from the ideal, but not enough to be considered poor. Grading companies like PSA, BGS, CGC, and TAG use precise measurement standards to determine centering subgrades, which impact the overall grade and card value.

What an 8.5 Looks Like

• Visibly uneven borders, but not severely misaligned
• Minor but noticeable off-centering on the front (and possibly back)
• Within a specific percentage threshold (often around 65/35 to 70/30, depending on the grader)

This grade means the card just missed the thresholds for a 9 or higher due to measurable centering issues.

Small Differences, Big Impact

Card grading is strict. Even a 1mm difference between the left and right or top and bottom borders can make the difference between a 9 and an 8.5 for centering. Here are key reasons:

• Printing Variations: Many cards leave the factory off-center.
• Human Error: Eyeballing centering is surprisingly inaccurate.
• Lack of Measurement: Submitting cards without precise centering checks.

Examples of 8.5 Centering

• One side border is noticeably thicker than the other
• Back centering (often overlooked) is slightly worse than the front
• Minor shift that doesn't meet the 60/40 or better threshold required for a 9

Section 3: How Grading Companies Judge Centering

Grading Standards by Company

Each grading company—PSA, BGS, CGC, TAG—has its own published standards for centering. Generally, the thresholds for an 8.5 are:

• PSA: Centering must be 65/35 or better on the front for an 8, 60/40 for a 9.
• BGS/CGC: Centering must be 70/30 or better for an 8.5, 60/40 for a 9.
• TAG: Uses digital measurement and assigns half-point increments with transparent reporting.

Front vs. Back Centering

• Front centering is usually weighted more heavily.
• Back centering thresholds are typically more lenient (e.g., 75/25 or 80/20).

Cards often get an 8.5 when the front is close to centered, but the back is slightly off. For more details on TAG standards, check TAG Centering Standards Explained.

Why Precise Measurement Matters

Estimating by eye is unreliable. A card that looks centered could actually be off by enough to lower its grade. To avoid an 8.5 for centering, use digital tools or measurement guides before submitting.

Best Practices for Measurement

• Use a ruler or digital caliper to measure all four borders in millimeters.
• Calculate the centering percentage (e.g., left border vs. right border).
• Compare with your grader’s standards (e.g., 60/40 for a 9, 70/30 for an 8.5).

Modern tools like Midpoint automate this process, instantly showing you if your card meets PSA, BGS, CGC, or TAG centering standards. This helps you make informed decisions before spending $30+ on grading fees.

Section 5: Avoiding 8.5 Centering Grades in the Future

Pre-Grade Your Cards

The best way to avoid an 8.5 centering grade is to pre-grade your cards with measurement tools before submission. This process helps you:

• Identify cards that truly meet the centering criteria for a 9 or 10
• Spot cards with minor off-centering, so you can skip grading them or adjust your expectations
• Increase your chances of higher grades and maximize card value

Steps to Take

• Scan or photograph your card in good lighting
• Use a measurement app like Midpoint for fast, accurate results
• Review both front and back centering

Conclusion

Getting an 8.5 for centering can be disappointing, but it’s usually due to minor measurement issues that are easy to miss by eye. Grading companies use strict standards, and small differences can impact your card’s grade and value. By understanding these criteria and using digital tools like Midpoint, you can take control of your grading outcomes. Always measure before you submit—your wallet and collection will thank you.

FAQ

Q: Why didn’t my card get a 9 for centering?

A:

Your card likely missed the 9 threshold due to slightly off-center borders—often as little as a 1mm difference can result in an 8.5 instead of a 9.

Q: Does back centering matter for the grade?

A:

Yes, but front centering is weighted more. If the back is significantly off, it can drop your centering subgrade even if the front looks good.

Q: How can I improve my chances of a higher centering grade?

A:

Use digital tools like Midpoint to measure before submitting. Only send cards that meet or exceed the 9 criteria for both front and back centering.
