The short answer is: there is no publicly available data on how many CGC 6 VSTAR Koraidon cards become SGC 9.5s. This specific conversion statistic simply does not exist in any grading company database, collector registry, or published report. When you cross-grade a card from one company to another—in this case, moving a CGC-graded card from CGC to SGC—there is no standardized formula predicting the outcome, and the results are highly variable from card to card.
The absence of this data reflects a broader reality in the Pokemon card collecting hobby: cross-grading statistics are not systematically tracked or made public by the major grading companies. Each card submitted for regrading is evaluated independently, with no guaranteed outcome based on its previous grade. A CGC 6 might become an SGC 9.5, an SGC 9, an SGC 8.5, or something else entirely—there is simply no aggregate conversion rate that has been measured and shared with the collecting community.

What Happens When You Cross-Grade Pokemon Cards Between CGC and SGC?
When you send a CGC-graded card to sgc for regrading, SGC’s graders evaluate the card fresh, without being influenced by CGC’s assessment. This means they are looking at the same physical condition, but applying their own grading standards and criteria. Different grading companies have different philosophies about centering, surface quality, corners, and other condition factors.
For example, SGC has historically been known for stricter centering standards than CGC, which could theoretically work against a card, but this varies from card to card and year to year. The reality is that you might see upgrades, downgrades, or the same grade when you cross-grade. Some collectors have reported upgrading CGC 6s to SGC 8s or higher on modern cards, while others have seen their cards downgraded. The lack of public data on VSTAR Koraidon specifically means you’re essentially taking a gamble, even though the physical condition of the card hasn’t changed.
Why Grading Company Conversion Data Remains Confidential
Neither CGC nor SGC publishes conversion rates or tracking data on how cards transition between their systems. This lack of transparency exists for several practical reasons. First, regrade attempts are typically small in volume compared to the overall population of graded cards, making it difficult to establish meaningful statistical patterns. Second, grading companies do not see competitive advantage in sharing this kind of detailed information.
Third, and most importantly, there is no standardized database that tracks individual collector submissions across multiple companies. The challenge with VSTAR Koraidon specifically is that this is a relatively newer card, and the population of cards graded in both CGC and SGC at higher grades may not be large enough to create reliable data. If only a handful of VSTAR Koraidon cards have ever been submitted to SGC after being graded by CGC, there would be no meaningful conversion statistic to report. Grading companies focus on publishing population reports—how many cards of a given type they’ve graded—not on tracking what happens to cards after they leave their vault.
The Population Problem for VSTAR Koraidon Cards
VSTAR Koraidon cards exist in the market, but they are not among the most frequently graded Pokemon cards. When you filter by a specific card, specific grading company (CGC), specific grade (6), and then add the requirement that those same cards were resubmitted to a different company (SGC) and received a specific grade (9.5), you’re looking at an incredibly narrow slice of the market. It’s quite possible that this exact scenario—CGC 6 to SGC 9.5—has only happened a handful of times, if at all.
To illustrate the scarcity: if CGC has graded 500 VSTAR Koraidon cards across all grades, and maybe 5% of those were graded at a 6, that’s 25 cards. Of those 25, how many were sent to SGC for regrading? Maybe one or two. And of those, how many became 9.5s? The numbers become so small that they’re not meaningful from a statistical perspective.
How Collectors Actually Track Cross-Grading Results
Since official conversion data doesn’t exist, collectors looking for this information need to try alternative approaches. The most direct method is to contact SGC or CGC directly and ask if they have any historical records of VSTAR Koraidon card submissions previously graded by their competitor. Some graders keep notes on submissions, though they may not share detailed data due to privacy concerns. Your next best option is to search specialized Pokemon TCG collector communities where anecdotal data accumulates.
Subreddits like r/PokemonTCG, forums like Blowout Cards Forums, and Elite Fourum sometimes have threads where collectors document their regrading experiences. Individual collectors who have sent CGC cards to SGC might share their results, though these stories are not systematic or comprehensive. You could also post a question in these communities asking if anyone has personally attempted this specific regrading and what result they received. While not a large sample, it’s more reliable than speculation.
The Subjectivity Problem: Why Grades Can’t Be Translated Between Companies
One fundamental reason why cross-grade conversion data is inherently unreliable is that grading itself is subjective. Two graders at the same company might disagree on a borderline card, and two companies definitely have different standards. SGC has historically focused on technical grading with an emphasis on centering, while CGC employs a different weighting system that factors in various condition elements differently. This subjectivity means that even if you had data showing “50 CGC 6 cards became SGC 9.5s,” that information would be misleading.
It suggests a pattern where none reliably exists. Any card that upgraded from CGC 6 to SGC 9.5 may have been on the cusp of that higher grade all along, or the SGC graders may simply have been more lenient that particular week. Conversely, a card that downgrades from CGC 6 to SGC 5.5 might have been graded loosely by CGC. The lack of data reflects this reality: there is no formula, no system, and no guarantee.
Real Examples From the Collecting Community
While specific data on CGC 6 VSTAR Koraidon to SGC 9.5 conversions doesn’t exist, collectors have documented isolated cases of cross-grading on other modern Pokemon cards. For instance, some collectors have reported sending CGC 7s of 2020-era Evolutions Charizards to PSA and receiving PSA 8s back. Others have sent BGS-graded cards to PSA and seen downgrades of a half-point or full point.
These anecdotal stories show the wide variation possible, but they also prove why aggregate data is so difficult to compile—every card’s journey is unique. The broader lesson from these examples is that cross-grading modern cards is inherently risky. Modern cards are easier to grade high due to better production standards, but the downside is that the grades are more sensitive to different company standards. A CGC 6 might be a solid, safe grade from CGC, but an SGC grader might push it to 6.5 or pull it back to 5.5 based on their own evaluation.
Future Data Availability and Market Evolution
As the Pokemon card market matures and more collectors engage in cross-grading, it’s conceivable that better aggregate data could eventually emerge. Third-party platforms like TCGPlayer, PSACard.com historical data, or emerging collector databases might eventually track regrade submissions. However, such data collection would require either the grading companies themselves to be more transparent or a third party to systematically track and publish results—neither of which is happening right now for cross-company conversions.
For now, and likely for the foreseeable future, the conversion rate of CGC 6 VSTAR Koraidon cards to SGC 9.5s will remain unknown. Individual collectors will continue to make their own decisions based on risk tolerance, card value, and personal preference for one grading company over another. The market will continue to function without this data point, because collectors have learned to evaluate cards and their grades based on condition observation rather than on statistical guarantees.
Conclusion
The question of how many CGC 6 VSTAR Koraidon cards become SGC 9.5s cannot be answered with real data because that data is not collected or published. Cross-grading is inherently unpredictable due to different grading standards between companies, and the population of cards in this exact scenario is likely too small to establish meaningful statistics.
Rather than seeking a conversion rate that doesn’t exist, collectors should base cross-grading decisions on the condition of their specific card and their goals in regrading. If you’re considering regrading a CGC 6 VSTAR Koraidon, focus on evaluating the card’s actual condition rather than hoping for a specific upgrade. The best approach is to research what SGC tends to do with similar cards in the Pokemon market, check collector forums for anecdotal feedback, and make an informed decision based on whether the potential upgrade is worth the submission cost and the risk of a downgrade or lateral move.
