Cracking Slabs: Why Do Grading Scores Change?

Cracking Slabs: Why Do Grading Scores Change?

🔁 What Is “Cracking and Reslabbing”?

“Cracking” refers to breaking a card out of its original graded slab, typically in hopes of:

  • Getting a higher grade on resubmission
  • Correcting what a collector believes was an inaccurate evaluation
  • Regrading with a different company known for higher sale premiums

But the growing trend is exposing a flaw: many resubmitted cards come back with different grades—sometimes multiple times. And not just from different companies. The same grader might give a different score weeks apart.

⚠️ Why Grading Inconsistencies Are a Serious Issue

Grading isn’t just about preservation. It’s now tied directly to financial value.

  • A 9.5 to a 10 bump on a key card can increase its market value by hundreds or thousands of dollars
  • Resellers use cracks and regrades to maximize returns
  • Casual collectors feel lost in a system where one-point swings feel arbitrary

Worse still, inconsistencies create a perception that grading is more about luck than objectivity. That perception erodes trust—and once trust is gone, the entire grading ecosystem suffers.

🧪 Why Are Grades Changing So Often?

Several factors contribute to this issue:

  1. Human subjectivity: Most companies rely on individual graders. Each grader may interpret corners, edges, or centering differently—even if following guidelines.
  2. Environmental variability: Lighting, magnification quality, and viewing angles may differ from one inspection to the next.
  3. Fatigue and volume pressure: Grading thousands of cards daily leads to natural variance in accuracy and attention to detail.
  4. Lack of transparency: Many grading companies provide only a final score—no breakdown, no data, no visuals. This makes it difficult for collectors to verify consistency.

🧠 How AGS Addresses Grading Inconsistencies

At AGS, we saw this problem coming. That’s why our entire grading process is built differently:

  • AI-driven evaluation ensures that lighting, measurements, and scoring are based on data—not human mood
  • High-resolution image analysis detects flaws with pixel-level precision
  • Every card gets a transparent breakdown of its condition—not just a single number

With AGS, the same card gets the same grade—every time. No regrade roulette. No second-guessing.

📉 What Grading Inconsistency Means for the Market

  • Flippers now exploit inconsistent grading for profit, submitting until they hit a favorable score.
  • Investors become cautious, unsure if their card’s grade actually reflects the true condition.
  • Collectors begin to lose faith, especially when crossover grading fails or big swings happen on minor flaws.

Ultimately, grading inconsistencies add uncertainty in a hobby that’s built on precision.
