So you’ve got a collection of trading cards sitting at home and you’re wondering if they’re worth anything. Maybe it’s a rare Pokémon card from your childhood, a shiny Premier League football card, or something you recently pulled from a pack. Whatever it is, getting it professionally graded could seriously boost its value and protect it for years to come.
But where do you even start? If you’re new to the hobby, the world of card grading can feel a little overwhelming. Different grading companies, confusing terminology, and a process that isn’t always clearly explained for UK collectors specifically.
That’s exactly why we put this guide together. We’re going to walk you through everything you need to know to get cards graded in the UK, from choosing the right grading company to submitting your cards and understanding your results. By the end, you’ll have a clear, simple roadmap to follow, even if you’ve never done this before. No jargon, no confusion, just straightforward steps to help you get started with confidence.
Why Get Your Cards Graded?
If you’ve ever wondered whether getting your cards graded is actually worth it, the numbers tell a pretty convincing story. The sports card grading market is currently valued at around USD 0.7 billion in 2025 and is forecast to reach USD 4.0 billion by 2036, growing at a compound annual rate of 17.5%. That kind of growth doesn’t happen by accident. It reflects a genuine shift in how collectors and investors think about trading cards, treating them less like childhood keepsakes and more like assets worth protecting.
The biggest reason people get cards graded might surprise you. According to market research, investment and collection preservation accounts for 41% of all grading end-use. That means most people submitting cards aren’t doing it purely for the display case. They’re doing it to protect long-term value and make their cards more credible to future buyers or traders. A professionally graded card comes sealed in a tamper-evident slab, carries an independent condition assessment, and signals to anyone looking at it that the card is authentic and has been properly evaluated.
TCG collectors are very much part of this wave. Pokémon has long been the dominant force in this space, but games like One Piece and Lorcana are rapidly building their own passionate collector communities, and demand for grading these cards is growing alongside them. If you’re sitting on pulls from any of these games, professional grading is one of the smartest ways to preserve and potentially grow their value over time.
What to Know Before You Submit
Before you send a single card off to get cards graded, it pays to understand exactly what graders are looking at. Professional grading assessments are built around four core attributes: centering, surfaces, edges, and corners. Centering refers to how evenly the printed image sits within the card’s borders. Surfaces cover scratches, print lines, and any marks on the front or back. Edges and corners are checked for wear, chips, or fraying. Once you know what graders are looking for, you can start evaluating your own cards more honestly before committing to a submission. According to this complete guide to grading your trading cards, choosing the wrong card to submit can burn money fast, so going in with realistic expectations matters.
Does the Maths Add Up?
This leads directly to the financial side of things. A good rule of thumb for beginners is simple: the likely graded value of a card should meaningfully exceed the combined cost of the grading fee and return shipping. If a card in a gem mint slab might sell for £40 but grading costs £20, the margin is thin once you factor in your time and any risk of a lower grade. Be honest about condition before you commit.
Inspect Before You Submit
Cards with factory print defects, manufacturing scratches, or miscuts will have those flaws reflected in the final grade. No grader overlooks them. Before submitting anything, inspect each card carefully under bright, direct lighting. Small surface marks that are invisible under normal conditions often become obvious under a lamp or torch. This step alone can save you from wasting a submission fee on a card that was never going to grade well.
The UK Grading Advantage
Some collectors are drawn to sending cards overseas, often chasing perceived resale liquidity in international markets. For Pokémon, One Piece, and Lorcana collectors specifically, though, this logic is worth questioning. UK collector communities are increasingly active and well-organised, and graded cards from reputable domestic services are genuinely valued within them. Beyond that, the practical costs of international submissions stack up quickly. You are looking at longer turnaround times, higher shipping costs, customs risk on the return journey, and currency conversion eating into your margins. For most UK-based collectors, a domestic grading option is not just more convenient; it is often the smarter financial decision overall.
Step-by-Step: How to Get Your Cards Graded with Imperium
Now that you know what graders are looking for, let’s walk through exactly how to get your cards graded with Imperium from start to finish. The process is straightforward once you know the steps, and this guide will take you through everything you need to do.
Step 1: Assess Your Cards
Before anything else, take some time to properly evaluate each card you’re thinking of submitting. Pick up your cards by their edges only, never touching the face or back with your fingertips, since even natural skin oils can leave marks that affect your grade. Hold each card under bright natural daylight or a clean LED light source and tilt it at different angles to catch any surface scratches, print lines, or holo defects that might not be obvious in dim lighting. Pay close attention to the corners for any whitening or fraying, run your eye along each edge for wear, and look carefully at the centering to see whether the border is noticeably wider on one side. Being honest with yourself at this stage helps you decide which cards are worth submitting and sets realistic expectations for the grade you might receive.
Step 2: Create Your Submission
Once you’ve selected your best candidates, head over to imperiumgrading.com and complete the submission form. You’ll log each card individually, choose your preferred service tier, and fill in the card details accurately, including the set, card name, and any relevant variant information. Taking care here matters because inaccurate details can cause delays and affect how your card is identified in the final report. Imperium currently grades Pokémon, One Piece, and Lorcana cards, so check that your cards fall within the supported TCGs before you submit. Double-check everything before confirming, as a clean, accurate submission makes the whole process smoother for both you and the grading team.
Step 3: Package and Send Safely
Protecting your cards during transit is just as important as the grading itself, and a little extra care here can prevent a lot of heartache. Start by sliding each card into a penny sleeve, making sure it sits flush without any bending or buckling. Then place the penny-sleeved card into a rigid top loader or card saver to give it a solid protective shell. Wrap your packaged cards in bubble wrap or foam padding before placing them inside a sturdy outer box, ensuring nothing can shift around during shipping. Always use a tracked and insured postal service when sending your submission; this protects you financially if anything goes wrong in transit and gives you peace of mind while you wait.
Step 4: The Grading Process
Once Imperium receives your submission, their graders get to work on a thorough technical assessment of every card. The process covers centering measurements with precise front and rear alignment percentages, surface analysis to identify scratches, print lines, and holo defects, and a detailed evaluation of edges and corners for any wear or whitening. Each card also goes through authentication verification to confirm it’s genuine and unaltered. Rather than just handing you a number, Imperium documents everything in a detailed digital grading report, breaking the assessment down into individual subgrade scores with clear reasoning for each. This level of transparency is a genuine step forward from the traditional approach of receiving a final grade with little context behind it.
Step 5: Custom Labelling and Encapsulation
After grading is complete, your card gets one of Imperium’s standout finishing touches: a custom hand-crafted art label created specifically for your submission. These labels aren’t generic stickers; they’re carefully designed to complement the card inside the slab and give your graded piece a polished, premium look. The labelled card is then sealed inside a UK-manufactured grading slab, meaning the entire process from grading to encapsulation happens right here in the UK. No international shipping delays, no customs complications, just a beautifully presented slab ready to display or sell.
Step 6: Receive Your Graded Slab and Digital Report
The final step is the most rewarding: getting your graded card back. Imperium returns your encased card alongside a full digital grading report that details every subgrade, lists any identified defects, and explains how the final grade was reached. Each card also receives a permanent certification number, which you can verify through Imperium’s Cert Lookup tool and cross-reference with their Population Report to see how your card compares within the wider graded pool. This combination of a beautifully encased slab and a transparent, detailed report gives you everything you need, whether you’re adding to your personal collection or building resale confidence with potential buyers.
What Makes a Good Grade? Understanding the Grading Scale
Professional grading uses a numeric scale running from 1 to 10, where a 10 represents a pristine, near-perfect card and anything below 6 typically indicates clearly visible wear or damage. Grades of 8 and 9 are still considered excellent, but the jump between a 9 and a 10 can be disproportionately large in terms of value, even when the physical difference is barely noticeable to the naked eye. Understanding where these thresholds sit before you submit helps you set realistic expectations and avoid disappointment when your results come back.
Centering is one of the most common reasons a card drops points, even when it looks flawless at first glance. It refers to how evenly the printed image sits within the card’s borders, and because centering is determined during manufacturing, there is nothing you can do to correct it. A card can have perfect corners, clean edges, and immaculate surfaces and still miss a top grade purely because the image is slightly shifted to one side.
Surface condition is equally critical, particularly for modern Pokémon, One Piece, and Lorcana cards. The foil and textured finishes found on many chase cards in these sets are especially prone to fine scuffing, even from light handling inside a sleeve. Print lines, light scratches, and gloss integrity all factor into this subgrade.
This is where Imperium’s detailed digital grading reports add real clarity. Rather than receiving a single number with no explanation, you get each subgrade broken down individually, so you can see precisely which attribute affected your final result. Heading into your first submission with a solid grasp of the grading scale makes that report far easier to read and much more useful going forward.
UK Grading vs. Sending Cards Abroad: What Actually Makes Sense
For most UK collectors, the decision to get cards graded often comes with a quiet assumption that sending cards overseas is the “proper” way to do it. That assumption is worth examining closely, because the practical reality in 2026 looks quite different.
The Hidden Costs of Going Overseas
Sending cards abroad for grading involves more than just the grading fee. You’re looking at international tracked and insured postage both ways, and with cards of any meaningful value, proper insurance isn’t optional. On top of that, post-Brexit import duties apply when your graded slabs return to the UK, and those costs add up faster than most collectors expect. Dedicated import tax calculators now exist specifically because this is a recognised pain point for UK collectors navigating cross-border grading. Factor in longer turnaround times at high-volume international services, and a submission that felt financially sensible can start to look like a much thinner margin than you planned for. For the majority of TCG collectors grading Pokémon, One Piece, or Lorcana cards at everyday values, those additional costs can genuinely outweigh the perceived benefits.
UK Grading Makes Practical Sense for Most Collectors
Within domestic UK communities, a professionally graded card at a 9 or 10 carries strong display and resale appeal, particularly for popular sets and chase cards from games like Pokémon, One Piece, and Lorcana, all of which have enthusiastic UK collector bases. UK-manufactured slabs and locally issued grading certificates also remove the friction of cross-border authentication entirely. There’s no need to verify overseas paperwork, and your cards never spend weeks in international transit where loss or damage is a real, if uncommon, risk.
Imperium’s custom hand-crafted art labels add something that goes beyond certification. Each graded card becomes a visually distinctive display piece, not just a certified collectible sitting in a generic case. That matters to collectors who take pride in how their collection looks on a shelf or in a case.
When Overseas Grading Still Makes Sense
To be fair, if you’re submitting an extremely high-value vintage card and your primary goal is maximum reach on the global secondary market, overseas grading may still be part of your strategy. But for the vast majority of collectors who grade for personal preservation, enjoyment, and domestic resale, a UK-based grader offers a faster turnaround, lower total cost, and an equally rigorous assessment process. As this 2026 grading guide puts it, understanding the full cost picture is the most important part of any grading strategy. For UK collectors, that full picture increasingly points closer to home.
Which Cards Are Worth Getting Graded?
Not every card in your collection deserves a trip to the grader, and knowing the difference between a smart submission and a wasted fee is one of the most valuable skills you can develop as a collector.
Rare and chase cards are your strongest candidates. In Pokémon, One Piece, and Lorcana, the cards that attract the most collector attention — think secret rares, ultra rares, and chase pulls — tend to see the biggest jump in value once graded at 9 or above. A card that sells for £40 raw can command significantly more in a graded slab, because buyers are paying for certainty around condition alongside the card itself.
Card type matters a great deal here. First edition prints, alternate art variants, full art cards, and secret rares consistently see the greatest grading premiums. When dozens of collectors own the same card, a verified grade is what separates yours from the rest on the secondary market. Condition becomes the differentiator, and professional grading makes that difference visible and trustworthy.
Fresh pulls deserve immediate protection. Cards pulled straight from sealed packs are typically in their best possible condition right at that moment. Sleeve them immediately, avoid touching the card surface, and keep them stored safely until you are ready to submit. Every hour of unprotected handling is a potential grade point lost.
Grading is not purely a financial decision. Beloved cards from a personal collection, childhood favourites, or pieces with sentimental history are entirely valid candidates for grading purely for preservation purposes. A sealed slab protects a card for decades.
If you are unsure whether a specific card justifies the cost, check its current ungraded market value against Imperium’s service fees before committing. The maths will usually give you a clear answer.
