There is no reliable probability data available to predict whether a CGC 6 Koraidon would receive an SGC 7.5 upon regrading. This isn’t because the data is hidden—it’s because the outcome depends almost entirely on the individual card’s condition rather than historical patterns or grade-to-grade conversion rates. Many collectors assume that moving from CGC to SGC follows predictable trends, but this assumption overlooks a fundamental reality: each card is evaluated independently, and the two companies use distinct grading criteria even though they both employ 10-point scales with half-point increments.
The honest answer is that your CGC 6 Koraidon could receive anywhere from a 5.5 to a 7.5 (or beyond) when submitted to SGC, depending on how that particular card measures up against SGC’s specific standards. While some collectors report improvements of 0.5 to 1.0 points when crossing grades, others see no improvement or even slight downgrades. This variance exists because grader interpretation, lighting conditions, and how each company weighs centering, corners, edges, and surface quality differ meaningfully.

How CGC and SGC Grading Standards Compare
Both CGC and SGC use similar numerical scales—a 10-point system with half-point increments—but the similarity in scale creates a false sense of equivalence. A CGC 6 is not automatically comparable to an SGC 6 because the companies have different threshold requirements for what constitutes each grade. For example, one company might be more lenient on surface wear while penalizing centering heavily, while another balances these factors differently. This is why regrading between companies is fundamentally a re-evaluation, not a conversion.
When you submit a card to a second grading company, you’re not applying a mathematical formula to your existing grade. You’re asking a different set of graders to assess that card from scratch using their own standards. In some cases, collectors have seen their CGC 6 Koraidons receive SGC 7 or even 7.5, but these instances are anecdotal rather than statistical. The critical variable isn’t what CGC determined—it’s whether SGC’s evaluation of that card’s actual condition aligns with their grade boundaries.
Why Individual Card Characteristics Matter More Than Statistics
The reason published cross-grading probability tables don’t exist is that they can’t exist at scale. Every Pokémon card has unique centering, corner wear, edge quality, and surface characteristics. A cgc 6 Koraidon with excellent centering but soft corners will grade differently than a CGC 6 with poor centering but sharp corners, even though both received the same initial grade. SGC’s evaluators may weight these factors differently than CGC did, leading to either improvement or disappointment. This is where many collectors get frustrated.
They see someone online report that their CGC 6 received an SGC 7.5 and assume that’s typical. In reality, that person’s card may have had condition characteristics that benefited under SGC’s specific criteria. Another collector’s CGC 6 with different wear patterns might receive a 6.5 from SGC, making the outcome feel completely random. The limitation here is that without physical inspection of your card by SGC’s graders, no one can meaningfully predict the outcome. Online forums and community discussions provide anecdotal data points, not predictive models.
What Collectors Actually Report From Cross-Grading Koraidon Cards
Community discussions on platforms like Blowout cards Forums and Reddit’s r/PokemonTCG reveal patterns, though not certainties. Some collectors report positive outcomes: a CGC 6 receiving an SGC 7 or occasionally a 7.5. Others report neutral outcomes, where the grade stays the same. A smaller number report downgrades, which surprises collectors who assumed regrading would never result in a lower grade.
These reports are valuable as snapshots of what’s possible, but they’re not predictive for your specific card. The Koraidon card specifically, being a popular Scarlet and Violet era card, has enough population data that you can find some cross-grading examples if you search actively. However, the sample size remains too small and too varied to establish reliable probability intervals. GemRate and similar population tracking services document grades and company distributions, but they don’t isolate “CGC 6 to SGC 7.5” outcomes as a measurable percentage. This gap in data reflects the reality that cross-grading outcomes are genuinely card-specific rather than grade-specific.
The Factors That Actually Determine Your Regrading Result
Rather than asking “what are the chances,” the more useful question is “what condition factors matter most?” SGC’s graders will evaluate your Koraidon on centering (how well the image is positioned), corners (sharpness and wear), edges (print quality and wear), and surface quality (scratches, wear, and printing defects). A CGC 6 means the card scored in a range that SGC might evaluate differently depending on how these factors distribute. For example, if your CGC 6 Koraidon was graded a 6 because of soft corners and moderate edge wear but excellent centering and surface, SGC might view that profile differently.
If SGC weights surface quality heavily and less heavily penalizes edges, your card could move up. Conversely, if SGC is stricter about centering or corners than CGC was, you might stay at a 6 or drop slightly. The comparison here is practical: you can inspect your card yourself and consider which grade companies are more likely to value your card’s strengths. If your card’s primary strength is surface quality, research which company is known for emphasizing that factor.
Common Mistakes Collectors Make When Anticipating Cross-Grade Results
The most frequent mistake is confusing optimism with probability. Many collectors submit a card to a second company expecting improvement because they’ve seen one positive example online, or because they feel the first company “graded them harshly.” This is backward reasoning. If you believe the first company graded correctly, then a second company’s standards will be different, not better—and “different” can cut either way. Submitting a card specifically to chase a higher grade is expensive (grading fees plus shipping) and has no guaranteed return. A second mistake is timing.
Some collectors believe that regrading at different times might yield different results, perhaps due to grader variation. While minor variation exists, it doesn’t follow a predictable pattern, so timing your regrading based on this belief is unreliable. A more significant warning: cross-grading has real costs. You’ll pay grading fees to SGC, wait weeks for results, and receive no refund if the grade disappoints. For a Koraidon card with uncertain upside potential, the financial math might not work unless the card’s current value is significantly lower than what an SGC 7.5 would command.
Where to Find Real Cross-Grading Data and Collector Feedback
If you want to research actual reported outcomes, start with community forums. Blowout Cards Forums has long-running threads where collectors discuss cross-grading outcomes and frustrations. Elite Fourum also hosts detailed discussions about regrading decisions. Reddit’s r/PokemonTCG and r/tradingcards have active threads where collectors post their regrading results and explain their reasoning.
These sources won’t give you probability percentages, but they’ll give you realistic examples of what happened with similar cards. GemRate provides population data showing how many Koraidon cards received each grade at each company, which helps you understand the grade distribution. This is useful context—if most CGC Koraidons are 6s and 7s, and most SGC Koraidons are 6.5s and 7s, you have some sense of the general quality and grading patterns. However, this population-level data still doesn’t predict individual outcomes. Your personal research task should be to find at least three reported examples of CGC 6 Koraidons regraded to SGC, examine those specific cards if images are provided, and compare their condition to your card.
The Future of Cross-Grading Transparency and Data
As the Pokémon card market matures and regrading becomes more common, the community may eventually accumulate enough data to identify real patterns. However, even with more data, predicting individual outcomes will remain limited because cards are unique.
What’s more likely to improve is transparency around factors: we might see better documentation of which grading companies weight specific condition factors most heavily, allowing collectors to make more informed decisions. Looking forward, the Pokémon card industry may move toward better cross-company standardization or toward collectors and investors accepting that once a card is graded by one company, regrading to another is a gamble rather than a strategic move. The smartest approach currently is to choose your initial grading company carefully, understanding their reputation and criteria, rather than planning a cross-grade upgrade as part of your investment strategy.
Conclusion
The bottom line is clear: there are no meaningful chances to estimate. A CGC 6 Koraidon could receive an SGC 7.5, but so could receive an SGC 6, 6.5, or 7. The outcome depends entirely on how SGC’s graders assess that specific card’s condition against their standards, which are different from (not better or worse than) CGC’s standards.
Expecting a predictable upgrade from one company to another is a common source of disappointment and wasted grading fees. Before you submit a card for cross-grading, research actual collector reports, inspect your card honestly for its strengths and weaknesses, and do the financial math. If the cost of regrading plus the risk of no improvement or downgrade makes sense for your card’s current value, proceed—but approach it as a re-evaluation, not as a probability bet. Your most reliable source of information will always be directly consulting grader feedback and learning which company’s standards favor your specific card’s condition profile.
