Quick answer: Card grading is a professional examination of a trading card under a grading company's own standards. If the card qualifies for the selected service, the result is recorded on a label and the card is sealed in a protective holder, commonly called a slab. A grade is one company's assessment, not a universal number, and it does not guarantee a higher resale price.

A card can be meaningful without being expensive, and expensive without being a good grading candidate. Before choosing a service or buying submission supplies, decide what you want grading to achieve: authentication, a condition assessment, a consistent display format or a possible resale benefit.

This guide explains the journey from a raw card to a graded holder. The aim is not to turn every card into a submission. It is to help you make deliberate decisions and protect the cards you choose.

What is card grading?

Professional grading combines an examination of a collectible with an assessment under a company's own standards. When an item qualifies for the selected service, the result is normally recorded on a label and the card is enclosed in a slab. Eligibility, authentication outcomes and grading scales differ between companies such as PSA, CGC, Beckett (BGS) and TAG.

A raw card is simply a card that is not currently encapsulated by a grading company. Raw does not mean damaged, counterfeit or inferior. A carefully protected raw card may be in excellent condition; a graded card may have significant wear that is accurately reflected in its grade.

Treat a grade as a specific company's assessment, not a universal unit that can be converted automatically into another company's number. Two labels carrying "10" may refer to different standards or designations.

What do card graders look at?

A useful way to organise your own inspection is around four areas: centering, corners, edges and surface. Beckett explicitly uses these categories for subgrades, while other companies describe condition through their own grading criteria.

  • Centering concerns how the printed design sits within the card's boundaries. A noticeably wider border on one side can matter, but design features are not always reliable measuring lines. Borderless artwork and deliberately asymmetric frames require particular care.
  • Corners deserve individual attention on the front and back. Look for bending, rounding, separation and small exposed areas of the underlying card stock.
  • Edges should be inspected along their full length, not just near the corners. Distinguish an observation such as "small white mark on the lower edge" from an unsupported conclusion such as "definitely factory damage".
  • Surface inspection includes the printed face, foil or textured finish and the reverse. A card that looks clean straight on may reveal a scratch or indentation as the light moves.

None of these observations gives you a guaranteed final grade. Use them to decide whether a submission still makes sense. Our guide How to Pre-Grade Cards explains a repeatable inspection method.

Authentication, card grades and autograph grades are different

A condition grade does not necessarily answer every question about a collectible. Autographs, altered cards, unusual materials and specialist issues may require different services or may not qualify for a numerical grade. A label may also distinguish the card's grade from an autograph assessment. Read the service description and the entire label, rather than focusing on the largest number.

A signed card raises at least two separate questions: what is the condition of the card, and what assurance is being offered about the signature? Do not purchase a standard card service expecting it to resolve both automatically.

Similarly, "Authentic" is not another way of writing "Gem Mint". It is a different type of result. Find out what the chosen service can issue before submitting a card with known alteration, restoration or unusual characteristics.

Why collectors grade their cards

There are several reasonable goals. You may want a favourite card presented consistently with the rest of a collection. You may want an independent condition opinion before selling. You may want authentication for a card whose exact identity or origin matters to you. Or you may simply value the experience of building a graded set.

Be clear about which goal matters most. A sentimental submission can be worthwhile even when the fee will not be recovered through resale. A commercial submission needs a more demanding calculation: expected proceeds after costs should justify the risk and the time the card will be unavailable. See Is Your Card Worth Grading? for a worked example.

Grading for preservation also deserves a comparison with good raw-card storage. Encapsulation is one option, not a reason to ignore handling, lighting and storage conditions. A slab does not make a card invulnerable.

When leaving a card raw makes sense

Keeping a card raw can be the right decision when you want to play with it, when you prefer a binder collection, when the grading cost dominates its likely value, or when no currently available service suits the card.

It can also be sensible to wait. An uncertain card identity, an unresolved shipping-insurance question or a rushed preparation session is a reason to pause, not a reason to improvise. "Not now" is a useful outcome: keep the card protected, record why you deferred it and reconsider when the missing information becomes available.

How card grading works: the journey from selection to return

1. Identify the exact card

Record the game or sport, year or release, set, card number, language, finish and variant. Include a serial number or signature details where relevant. A familiar character name is not enough to distinguish every printing. For modern TCGs such as Pokémon or One Piece, pay particular attention to alternate artwork, promotional stamps and regional language editions. For sports cards, note parallels and numbered variations. Photograph both sides so the record remains useful after the card leaves your possession.

2. Inspect and decide

Use a repeatable inspection routine. Record visible concerns and compare realistic outcomes with your reason for grading. Do not assume a newly opened card is flawless, or that an attractive scan shows everything a grader may examine.

3. Choose the grading company and service

Confirm that the exact card type is eligible. Then compare the label, reporting options, current service availability, value limits, submission route and total cost. The right answer for an English Pokémon card may not be the right answer for a German-language card, a thick memorabilia card or a vintage issue. Read current instructions for the route you will actually use: a dealer, a domestic grading office and an international direct submission are not necessarily the same process. Our comparison PSA vs BGS vs CGC vs TAG helps you choose.

4. Prepare, document and pack

Preserve the card's current condition rather than trying to improve it. Work with clean, dry hands, an uncluttered surface and properly fitting protection. Keep each card connected to its inventory entry as you prepare the package. Storage preferences do not overrule submission requirements: the best sleeve-and-holder combination for your binder or display may not be the combination your chosen grader requests.

5. Track the order and check the return

Save the order confirmation, payment record, packing list and shipping details. After return, match the cards and certificates to your inventory, inspect the holders and review any discrepancies promptly. Our after-grading guide provides a practical return-check routine.

What card grading does not promise

A higher resale price is not guaranteed. A grade does not eliminate market risk, selling fees or the possibility that a card is difficult to sell. Nor does protective packaging guarantee a particular result: a sleeve can help avoid new handling damage, but it cannot erase existing wear.

A database match is useful but not sufficient proof that a slab in front of you is genuine. PSA specifically warns that a valid certification number alone does not remove counterfeit risk. Compare the physical item, label details and available images as well.

Finally, an estimated turnaround should not be treated as a firm date for a planned sale. Leave room for receiving, research, processing and transport rather than building a commitment around the most optimistic timeline.

Frequently asked questions

Can a card be worth grading even with visible damage?

Yes, depending on your objective. Authentication, sentimental value or completion of a collection may matter more than a high numerical grade. For a resale decision, compare the likely lower-grade outcome with the raw alternative instead of using a top-grade price.

Does better protection improve the grade?

No. Protection is about avoiding additional damage. It does not change the card's existing condition or guarantee how a grader will assess it. Buy supplies for appropriate fit and handling, not a promised number.

Should every expensive card be graded?

No. Eligibility, the card's current condition, your intended use, the cost of the selected service and the risks of sending it away all matter. Consider each card individually.

What is a raw card?

A raw card is any card not currently sealed in a grading company's slab. The term says nothing about its condition or authenticity.

Start with one well-planned submission

For a first submission, choose a manageable number of cards whose identity and purpose you understand. Establish a record-keeping and handling routine before scaling up. The best first result is not necessarily a 10; it is a submission you can account for from start to finish. Save the Grade.
