The honest answer is that specific data on how often pre-release Miraidon cards receive higher grades after regrading does not exist in publicly available sources. Neither PSA, CGC, nor BGS publishes regrading statistics broken down by specific cards or sets, which means any claim about pre-release Miraidon regrading rates would be speculation rather than fact.
However, what we do know from broader grading data suggests that regrading success depends far more on individual card condition and the margin between original and target grades than on the card’s identity or pre-release status. If you own a pre-release Miraidon card and are considering regrading, the decision should hinge on whether the current grade appears conservative compared to the card’s actual condition, not on historical success rates that simply aren’t tracked or published. The economics of regrading have also shifted dramatically as PSA and CGC premiums have narrowed from their 2021 peaks to just 5-10% on modern cards today, meaning the financial case for regrading is much weaker than it was a few years ago.

Why Regrading Data for Specific Cards Remains Hidden from Collectors
The grading companies treat regrading statistics as proprietary business information. PSA maintains extensive population reports through their CardFacts® database, but these reports show only the distribution of cards at each grade level for a given card—they do not reveal how many cards were resubmitted, how many improved, or what percentage achieved higher grades. CGC and BGS follow similar practices. This opacity exists partly for competitive reasons and partly because regrading data could be used to reverse-engineer grading consistency, something these companies prefer to control internally.
For pre-release Miraidon cards specifically, the card pool is small enough that even if PSA wanted to publish regrading rates, doing so might violate collector privacy or reveal information that sophisticated collectors could use to game the system. A serious collector with inside knowledge of how often pre-release Miraidon cards move from PSA 8 to PSA 9, for instance, could make more informed decisions about which cards to resubmit and when. The grading companies have little incentive to share this advantage with the broader market. What you can do instead is check PSA’s CardFacts® for pre-release Miraidon #13 to see the population distribution at each grade level. A heavily weighted distribution toward one grade might suggest that grade is the natural ceiling for the card, while an unusual spread across grades could hint at grading variance—though this still won’t tell you your specific chances on resubmission.
Understanding Pre-Release Miraidon Cards and Their Grading Context
Pre-release Miraidon cards (promotional #13 from the Scarlet & Violet era) command premium prices due to their exclusivity and limited distribution, but this prestige doesn’t automatically translate to easier grading or more forgiving evaluations. In fact, the opposite can be true. High-profile promos and first-edition cards often face more scrutiny during grading because they’re already known to be valuable. Graders may be more critical of centering, corners, and surface wear on a card they recognize as desirable, knowing that collectors will scrutinize their work. The current market for pre-release Miraidon cards reflects the general cooling in Pokemon card prices since 2021-2022.
A pre-release Miraidon in PSA 9 or PSA 10 condition still commands respectable premiums, but the gap between a PSA 8 and PSA 9 has narrowed considerably. Research from 2026 shows that PSA and CGC premiums on modern cards now average just 5-10%, meaning the cost of regrading (typically $15-50 per card depending on turnaround time) may not justify the potential gain if you’re only hoping to move from an 8 to a 9. A critical limitation here is that pre-release Miraidon cards, while desirable, are not old enough to have accumulated significant historical regrading data. Collectors have been regrading vintage cards for decades, but pre-release promos from 2023 have only had a few years of regrading history. Any patterns that emerge now might not hold true as more examples are submitted and grading standards potentially shift.
What General Regrading Success Rates Tell Us About Your Chances
Broader data on Pokemon card regrading does exist, though it’s not card-specific. An analysis of 840 Pokemon cards graded in February through April 2026 found that 90% scored grade 7 or higher, with only 1.2% predicted to achieve a PSA 10. This data suggests that most cards cluster in the grade 8-9 range, which is where pre-release Miraidon cards typically fall when they’re worth grading at all. Cards that reach these mid-to-high grades usually represent clean, well-handled examples with no significant defects—exactly the type of card that would be a reasonable candidate for regrading if you suspect the original grade was too conservative. However, the 1.2% prediction rate for PSA 10 should give you pause if you’re hoping to regrade a card from PSA 9 to PSA 10.
That threshold represents a dramatic quality leap. The difference between an 8 and a 9 might hinge on minor centering or a light surface imperfection, but the jump to 10 requires a card that is essentially flawless in the eyes of the grader. For a pre-release Miraidon, if it came back as a 9 originally, achieving a 10 on regrade would require either grader inconsistency (which does happen) or hidden improvement you didn’t notice yourself—both are relatively rare outcomes. A realistic example: you pull a pre-release Miraidon from a box, sleeve it immediately, and keep it in a binder. It gets graded PSA 8, and you suspect the centering or corners were undervalued. A regrade might bump it to PSA 9 if the grader’s second opinion is more generous—but this still represents a maybe 20-30% chance at best based on general regrading patterns, not the specific guarantee many collectors hope for.
The Economics of Regrading Pre-Release Miraidon Cards Today
The financial case for regrading pre-release Miraidon cards is weaker in 2026 than it was four years ago, when PSA premiums could exceed 20% and demand was at its peak. Today’s 5-10% premium means that moving a card from PSA 8 to PSA 9 might increase its value by $15-50 depending on current market price, while the regrading itself costs $15-50. You’re essentially break-even or slightly profitable if the regrade succeeds, but you lose money if it comes back at the same grade or lower. This economic reality should drive your regrading decision, not nostalgia for the boom market of 2020-2021. If you have a pre-release Miraidon in PSA 8 that you’re seriously considering regrading, pull current market data from a site like the price guide or TCGPlayer to see what PSA 8 and PSA 9 copies are actually selling for.
Calculate whether the difference justifies the regrading cost and the risk that the card returns at the same grade or, in rare cases, at a lower grade. Most collectors today will find that the math simply doesn’t work unless they have a very strong conviction that the original grade was wrong. A comparison worth making: regrading decisions are more justified for older, high-value cards (such as vintage Base Set holos) where premiums can exceed 20-30%, than they are for modern promos like pre-release Miraidon. Modern cards have tightened grading standards, smaller premiums between grades, and a much higher risk of coming back at the same grade. If you wouldn’t regrade a pre-release Sword & Shield promo, you probably shouldn’t regrade pre-release Miraidon either.
Common Pitfalls and the Risk of Grade Compression
One overlooked risk when regrading is that the card might come back at a lower grade than the original submission, even if it hasn’t deteriorated. This phenomenon, sometimes called “grade compression,” occurs when a second grader applies stricter standards than the first, or when the card has developed minor wear between submissions (handling, light, humidity). For a pre-release Miraidon, this risk is real and often underestimated by collectors excited about the prospect of upgrading. Another pitfall is submitting for regrading during periods when grading companies are backed up or deprioritizing submissions.
If your pre-release Miraidon sits in a PSA or CGC queue for months before being regraded, the additional handling and time introduce environmental risks. Cards stored in submission trays with inconsistent humidity or temperature control can shift subtly in condition, and you may receive a lower grade not because the grader was stricter, but because the card actually changed during the waiting period. A final warning: do not assume that because pre-release Miraidon cards are desirable and valuable, they are immune to the economic realities of regrading. High demand actually increases the incentive to regrade speculatively, which means the regrading pool for Miraidon may include more marginal candidates—cards that probably shouldn’t have been submitted in the first place. This increased competition for positive outcomes may make it psychologically harder to accept a regrade that comes back at the same level.
Using PSA CardFacts to Estimate Your Regrading Odds
The closest thing to real data available to collectors is PSA’s CardFacts® population reports. For pre-release Miraidon #13, you can search CardFacts and see the distribution of cards across all grades. If the population report shows, for example, 500 copies graded as PSA 9 and only 50 as PSA 10, that’s a rough indicator that the PSA 9 tier is the common ceiling.
It doesn’t tell you about regrading specifically, but it does suggest that achieving a 10 is statistically difficult, which is relevant when you’re considering whether to submit. Conversely, if you see an unusual distribution—many cards at PSA 8 and relatively few at PSA 9—this could hint that grading variance exists and a regrade has a meaningful shot. However, this interpretation is speculative and can easily lead you astray. Distributions can reflect market incentives (perhaps collectors stopped submitting once prices cooled) rather than grading difficulty.
The Future of Pre-Release Card Regrading Economics
As grading companies continue refining their processes and building more data, the ability to identify consistently undergraded cards will likely improve. PSA and CGC have introduced new grading subgrades in recent years that provide more transparency about centering, corners, and surface quality separately from the final numeric grade. This increased granularity should theoretically make regrading decisions more informed, but it also means that a card graded as PSA 8 with poor centering today might legitimately deserve an 8, not because of inconsistency but because the breakdown justifies the grade.
For collectors holding pre-release Miraidon cards, the long-term play is unlikely to center on regrading profits. Pre-release promos from the early 2020s will eventually become vintage by 2040s standards, but by then, regrading economics may have shifted entirely. For now, the safer strategy is to view regrading as a measure of confidence in your card’s condition relative to the original assessment, not as a financial arbitrage opportunity.
Conclusion
Pre-release Miraidon cards do not have publicly available regrading statistics, and no collector or analyst can tell you a specific success rate for upgrading them to higher grades. The broader Pokemon card market suggests that regrading success rates vary widely based on individual card condition, the margin between current and target grades, and grading variance—with most improvements occurring between adjacent grades like 8 to 9 rather than larger jumps.
The economics of regrading modern cards like pre-release Miraidon have deteriorated significantly since the 2021 peak, with current PSA and CGC premiums at just 5-10%, meaning your primary motivation should be correcting a perceived grading error rather than chasing financial gains. Before submitting a pre-release Miraidon for regrading, verify the current market price for your card at its current grade and the grade you hope to achieve, confirm that the difference justifies the regrading cost, and be honest about whether the original grade was truly conservative or simply accurate. If you decide to regrade, check PSA’s CardFacts for population data on your specific card to understand the baseline difficulty, and accept that success is uncertain regardless of how flawless your card appears to you personally.
