The odds that a CGC 9 will be reevaluated as a PSA 10 are relatively low—somewhere in the range of 5 to 15 percent based on collector experiences and data from cross-graded submissions. While it happens, it’s not common because both grading companies use similar technical standards, and a card that barely missed a 10 from one grader is unlikely to exceed expectations from another. CGC and PSA both grade on a 1-10 scale with published criteria, and their definitions of a 10 are nearly identical: a virtually flawless card with pristine centering, corners, edges, and surface condition.
The key reason this reevaluation is rare relates to consistency in how the cards themselves present. A card with a small printing defect, a faint crease, or slightly loose centering that resulted in a CGC 9 will likely show those same issues to a PSA grader. The grading company might change, but the physical card hasn’t. That said, grading can be subjective at the margins, and factors like lighting conditions, the specific grader’s experience, and even the exact angle of inspection can occasionally produce different results.

How CGC and PSA Grading Standards Compare
cgc Grading Services entered the pokemon card market in 2020, which was significant because PSA had dominated sports card and Pokemon grading for decades. Both companies assess cards using the same foundational criteria: centering (how the image sits within the borders), corners (sharpness and wear), edges (clarity and condition), and surface (print spots, scratches, or other flaws). A PSA 10 or CGC 10 represents the same ideal: an exceptional card with virtually no visible defects under normal viewing.
The practical difference lies in how strictly each company applies these standards on any given day. Some collectors report that CGC tends to grade slightly more generously in certain categories, particularly centering, which has led to speculation that a CGC 9 might have a chance with PSA. However, data from the Pokemon Card Market Research forum and cross-grading experiments suggest this is overstated—if anything, modern PSA grading has become more consistent, not more lenient. The real factor in any successful reevaluation is usually margin of error at the boundary between grades, not systematic difference in standards.
Why the Jump from 9 to 10 Is Particularly Difficult
The difference between a 9 and a 10 is the narrowest gap on the grading scale, which is why cross-grade success at this level is so low. A psa 10 or CGC 10 card must meet an exceptionally high bar—corners must be nearly razor-sharp, centering must be within 55/45 or better, and the surface must be pristine. A card graded 9 has already been identified as falling slightly short, typically due to one flaw that breaks the 10 standard. That might be a corner with the slightest touch of wear, centering that’s off by a millimeter, or a barely visible print spot.
When a collector submits a CGC 9 to PSA hoping for a 10, the card is being held to the same standard it already failed once. Unless the graders disagree fundamentally on what they’re seeing—which occasionally happens but is genuinely rare—the result will be the same or lower. The inverse is also true: a PSA 10 submitted to CGC will almost always come back as a CGC 10. The real risk in cross-grading a 9 is actually receiving a PSA 8, which happens in roughly 10-20 percent of cases where collectors try this. This downgrade is the financial nightmare that deters most serious collectors from cross-grading marginal cards.
Real-World Examples of Cross-Grading Outcomes
One documented case involved a CGC 9 of a 1999 base Set Charizard that was submitted to PSA through a collector’s group break. The card was noted for exceptional centering but had a single print spot on the back. It came back as PSA 9, identical to the CGC grade. The print spot was the limiting factor for both companies.
This outcome is typical: the same flaw that prevented a 10 from one grader prevents it from another. There are exceptions. A CGC 9 of a Blastoise Base Set card was reportedly resubmitted to PSA and returned as PSA 10, but this card had been closely inspected by collectors and appeared to be a borderline case—likely a genuine 10 that one grader had marked down due to fatigue or a different interpretation of a minor surface imperfection. These successes are memorable precisely because they’re uncommon. Far more frequently, collectors who cross-grade CGC 9s receive PSA 9s or drop a full grade, turning a $500-1000 card (CGC 9) into a $200-400 card (PSA 8).
Should You Cross-Grade a CGC 9 to PSA?
For most collectors, submitting a CGC 9 to PSA is not a sound financial decision. The cost of grading, shipping, and insurance typically runs $50-150 depending on service level and turnaround. To break even on this investment, the card would need to gain approximately $100-200 in value from the grade change alone. A CGC 9 to PSA 10 jump might theoretically do this for premium cards—a Base Set Charizard CGC 9 selling for $1,200 might fetch $2,500 as a PSA 10—but that assumes the reevaluation succeeds. If it comes back as PSA 9 (the most likely outcome), you’ve lost your grading fee and the card is no more valuable.
If it downgrades to PSA 8, you’ve actively harmed the card’s marketability. The one scenario where cross-grading makes sense is if you believe the CGC grade was genuinely harsh or incorrect, and you have specific reasons to think another grader will see the card differently. This might apply if the card has unusual characteristics—perhaps the centering appears off due to how it’s positioned in the slab, or you’ve identified a defect you think the original grader missed. Even then, the risk-reward is unfavorable unless you’re willing to lose money. PSA does not charge a premium for cards that cross-grade successfully, and neither does CGC. A PSA 10 and a CGC 10 of the same card should theoretically trade at similar prices, though in practice, some collectors have personal preferences for one company over another.
The Risks and Limitations of Cross-Grading
The biggest risk is downgrading, which happens frequently enough that serious collectors approach cross-grading with caution. A PSA or CGC grader reviewing a card a second time has different eyes, potentially different standards on that day, and no obligation to match the previous grade. Some grading companies are stricter than others in different eras—PSA’s standards in 2024 are notably tighter than they were in 2015, for instance. A card that received a PSA 9 in 2018 might have been graded more generously than current PSA 9s, which could work against you if you’re hoping for a 10.
Another limitation is that cross-grading doesn’t actually improve the card itself. You’re not changing any physical attribute; you’re just paying for a different opinion. If the card has a centering issue, a print defect, or a surface flaw that caused the 9 grade, no amount of re-grading will fix it. Additionally, frequent re-grading can actually harm a card’s provenance and market perception. A card that shows up in the market as “CGC 9 → PSA 9” or worse “CGC 9 → PSA 8 → CGC 9” looks like the owner was hunting for a better grade, which raises questions about whether the card is a genuine candidate for a higher grade or just a marginal example being submitted repeatedly.
Market Perception and Resale Value
How the market perceives different grading companies affects whether a CGC 9 or PSA 9 of the same card sells for different prices. Historically, PSA 10s command a premium because of PSA’s longer track record and institutional trust among collectors. A PSA 10 Base Set Charizard might sell for 15-25 percent more than an equivalent CGC 10. This gap has narrowed in recent years as CGC’s reputation has solidified, but it persists for high-value cards.
This market preference is the real reason some collectors are tempted to cross-grade—the hope that a PSA label will increase the sale price. The market does not, however, reward the cost of failed cross-grading attempts. If you spend $100 submitting a CGC 9 to PSA and it returns as PSA 9, you’ve absorbed that $100 cost, and the card is no more valuable. If it downgrades to PSA 8, you’ve actively destroyed $300-500 in card value while spending $100 on grading. Smart collectors factor this math into their decisions and usually decide to keep CGC 9s in their original holders, especially for cards where the grade differential isn’t worth the risk.
The Future of Multi-Service Grading and Standards Convergence
As both CGC and PSA have matured their Pokemon grading services, the gap in grading standards has narrowed. Both companies now use published, transparent criteria, train graders extensively, and implement quality control measures. This convergence means that cross-grading outcomes are increasingly predictable—a CGC 9 is likely to remain a 9 or drop to an 8 if submitted to PSA, because both companies are assessing the same card against similar standards.
Looking ahead, the Pokemon card market may continue to develop a preference for certain grading companies based on factors beyond strict grading standards—brand reputation, slab design appeal, or market momentum. However, this preference won’t change the reality that a card graded 9 by one company is unlikely to jump to 10 by another. Collectors who want a 10 are better served by acquiring cards already graded as 10s, which have already passed the higher standard.
Conclusion
The odds that a CGC 9 will be reevaluated as a PSA 10 remain low, realistically between 5 and 15 percent, because grading standards between the two companies are similar and the gap between a 9 and 10 is the narrowest on the scale. A card identified as falling slightly short of a 10 by one grader will likely be seen the same way by another unless there’s a genuine disagreement about what the graders are observing—which is uncommon. For most collectors, the practical lesson is clear: don’t cross-grade CGC 9s expecting a PSA 10.
The financial risk is significant, the odds of success are low, and the cost of failure can damage a card’s value. If you own a CGC 9 of a card you love, keep it in its original holder. If you want a PSA 10, purchase one directly. This approach is financially sound and avoids the disappointment and cost of a downgrade.
