There is no specific documented process for crossing an HGA 7 Calyrex card to BGS publicly available from either grading company. However, the general practice of crossover grading—submitting a card already graded by HGA to BGS for re-evaluation and potential re-slabbing—follows the established procedures that BGS uses for all crossover submissions. If you have an HGA-graded Calyrex card, BGS will accept it for their standard crossover service, extract it from the HGA slab, clean and evaluate it using their own grading standards, and place it in a BGS slab if it meets their acceptance criteria.
The critical point to understand is that crossing over to BGS offers no guarantee your card will receive the same grade or even remain in the same numeric range. The crossover process exists because different grading companies use different technology, subgrades, and evaluation criteria. BGS’s detailed subgrades and half-point increments (allowing grades like 8.5) differ significantly from HGA’s grading methodology, which relies on advanced imaging sensors to measure centering and surface quality to the micron level. Collectors sometimes pursue crossovers to potentially achieve a higher grade, access BGS’s specific slab format, or diversify their graded card collection, though these reasons come with substantial risk of the grade going down.

What Is Card Grading Crossover and Why Collectors Submit Cards?
Card grading crossover is the process of taking a card that has already been professionally graded and slabbed by one company—in this case HGA—and submitting it to a different grading company like BGS for an independent re-evaluation. The first company’s slab is broken open, the card is cleaned and inspected to BGS’s standards, and then it is re-graded and placed in a BGS slab. This is a common practice in the trading card hobby, offered by all major grading companies including PSA, BGS, CGC, and CCC Grading. Collectors pursue crossovers for several reasons.
Some believe a different grading company might assess the card more favorably based on their technology or grading philosophy. Others want access to BGS’s specific slab design or their detailed subgrades that break down centering, corners, edges, and surface separately. Still others are building collections that deliberately include cards graded by multiple companies. Regardless of motivation, the crossover carries significant financial and emotional risk because there is absolutely no guarantee the card will receive the same numeric grade from BGS as it received from HGA.
Understanding HGA’s Grading Technology and Standards
HGA uses advanced imaging sensors to measure centering and surface flaws down to the micron level, which eliminates much of the human subjectivity that traditionally plagued card grading. Their technology analyzes cards with precision equipment that detects imperfections invisible to the naked eye, resulting in grades that are highly consistent within HGA’s own ecosystem. If your Calyrex was graded a 7 by HGA, that assessment was made using this automated imaging technology combined with professional human review.
The limitation of HGA’s system becomes apparent when crossing over: bgs uses a fundamentally different approach. BGS relies on trained human graders applying their own experiential standards to assess cards across four key subgrades. HGA’s extreme precision in detecting microscopic surface flaws means that a card HGA graded as a 7 might be viewed by BGS graders as having flaws that warrant a lower grade, or conversely, the same wear that HGA’s sensors flagged might be deemed less severe by BGS’s standards. This is not a criticism of either company—it reflects that card grading involves subjective judgment even when technology is involved, and different companies weight different factors differently.
BGS Grading Scale and Subgrading System
BGS uses a 1-10 scale with half-point increments, meaning a card can receive a grade of 6, 6.5, 7, 7.5, 8, and so on. This granularity is one reason collectors are attracted to BGS slabs—the half-point grades feel more precise than whole-number scales. More importantly, BGS provides detailed subgrades for each card: Centering, Corners, Edges, and Surface. These four subgrades are visible on the BGS holder and give collectors specific information about which aspects of the card’s condition are strong and which are weak.
If your HGA 7 Calyrex crosses over to BGS, you would receive subgrades for each of those four categories. For example, you might get a BGS 7 overall with subgrades of Centering 7, Corners 6.5, Edges 7, and Surface 8. Or you might receive a BGS 6.5 if the crossover evaluation reveals wear that HGA’s assessment either weighed less heavily or didn’t detect. The subgrades provide transparency about the card’s strengths and weaknesses, but they also mean you’re getting a completely fresh assessment by different experts using different criteria.
The Actual Process for Submitting a Crossover
To cross over your HGA 7 Calyrex to BGS, you would first access BGS’s submission portal and select their crossover service option from their available grading categories. You’ll need to declare the card’s current HGA grade, provide the HGA certification number if known, and select your turnaround time preference—BGS offers standard, rush, and faster options at different price points. The fee for a crossover is typically lower than the fee for a standard grading submission because BGS does not need to assess the card’s authenticity (that’s already been verified by HGA). You then ship the card in its HGA slab to BGS according to their shipping instructions.
BGS will receive it, log it into their system, remove it from the HGA holder, clean it, and have it graded by one of their trained graders. The entire process typically takes 2 to 8 weeks depending on the turnaround time selected and current BGS volume. Once grading is complete, your card arrives in a BGS slab. Importantly, BGS is under no obligation to accept the card for grading even if HGA graded it; in rare cases, BGS might decline a card if they identify authenticity concerns or damage too severe to grade. This is uncommon but possible.
The Risk of Grade Drop and Why There Is No Guarantee
The most important reality of crossing over is that there is no guarantee—zero—that your HGA 7 will become a BGS 7 or higher. In fact, grade drops are common enough that they’re expected and discussed openly in collector communities. A card that HGA graded as a 7 might receive a BGS 6, 6.5, or even lower depending on how BGS graders assess the centering, corners, edges, and surface. Conversely, the card might receive a BGS 7 or even BGS 7.5, but this is never guaranteed and shouldn’t be expected.
This grade inconsistency exists across all major grading companies. PSA, BGS, CGC, and HGA each use slightly different standards and technologies, and a card graded PSA 8 by one expert might receive a CGC 7.5 by another. This reality means that crossing over is fundamentally a risky decision made for reasons other than guaranteed grade improvement—reasons like wanting BGS’s specific slab format, accessing their detailed subgrades, or diversifying a collection. Never cross over expecting a grade bump; it’s a best-case scenario, not an expectation.
Special Considerations for Pokémon Cards and Modern Calyrex Cards
Pokémon cards present specific challenges for crossover grading because the hobby has exploded in popularity and grading standards have become stricter over time. Calyrex cards, released in 2020-2021 as part of the Sword and Shield expansion, are relatively modern cards with production characteristics that contemporary graders understand well. However, this also means that different grading companies may have refined their standards since HGA’s original assessment. Modern Pokémon cards are scrutinized heavily for centering, print lines, and surface quality, and standards between 2020-2021 and 2026 may have shifted.
A specific example: an HGA 7 Calyrex from a 2021 submission might have been assessed under HGA’s earlier standards when the modern Pokémon market was less competitive. If you cross that same card to BGS in 2026, BGS graders are evaluating it by current standards and current expectations for what a 7 should represent. This could work in your favor if BGS considers the card generous for a 7 by modern standards, but more likely it means the current market context might result in a lower grade. Additionally, Pokémon cards with print lines or centering issues—common on modern Pokémon cards—may be re-evaluated differently by BGS’s visual assessment process compared to HGA’s micron-level sensor technology.
Industry Changes and the Future of Crossover Grading
The landscape of card grading is shifting after Collectors Holdings announced an agreement to acquire Beckett (which owns BGS) in December 2025. This consolidation may eventually affect crossover policies, service timelines, and potentially the criteria BGS uses for future crossover submissions. While crossovers continue to be accepted as of 2026, future changes to BGS’s parent company ownership could influence how they handle cards graded by competitors.
As a collector considering a crossover, it’s worth monitoring official announcements from both HGA and BGS regarding any policy changes. The consolidation might create opportunities for streamlined services or it might introduce new restrictions. For now, crossovers remain available and functional, but the timing of the Collectors Holdings acquisition makes it prudent to submit any crossovers you’re seriously considering sooner rather than later, in case policies shift.
Conclusion
Crossing an HGA 7 Calyrex to BGS is possible through BGS’s standard crossover service, but there is no special or unique process specific to Calyrex cards or to the HGA-to-BGS crossover path. You would submit the card through BGS’s online portal, select the crossover option, pay the crossover fee, ship the card in its HGA slab, and wait for BGS to grade it and return it in a BGS slab. The fundamental risk is that your grade may change—up or down, but most commonly down—because HGA and BGS use different technology and grading standards. Before you pursue this crossover, honestly assess your reasons.
Are you seeking a grade guarantee? Don’t expect one; it doesn’t exist. Are you wanting BGS’s specific slab format or detailed subgrades? That’s a legitimate reason to cross over, but accept that the grade might drop and factor that risk into your decision. If you decide to proceed, contact BGS directly or consult active Pokémon card collecting communities for the most current submission procedures and recent experiences from collectors who have crossed over modern Pokémon cards. Their real-world insights will be more valuable than any general guide.
