Sports cards are graded by third-party companies such as PSA, SGC, Beckett, and CGC, not by a league or card manufacturer. Each company uses trained staff and its own grading standards to assess a card’s condition and authenticity.
If you are trying to identify a grading label, understand who assigned a grade, or choose a service for your own card, the company name on the slab is the best place to start. Here is how the major graders differ, what their grades mean, and what to check before sending a card in.
Who graded sports cards in the professional era?
Professional grading companies inspect and authenticate cards, then seal them in protective holders called slabs. The name and logo printed on the holder identify the company responsible for the grade.
Common names include Professional Sports Authenticator (PSA), Sportscard Guaranty (SGC), Beckett Grading Services (BGS), and CGC Cards. These are separate grading services with their own standards and procedures. The grade is the service’s assessment, not an official rating from a sports league or card maker.
It is usually more useful to ask which company graded a card than to look for a specific grader’s name. Companies generally do not identify the individual employee who examined each card. Their processes and how much information they disclose can differ, and a label typically names the grading service rather than the person who handled the card.
That distinction matters because a prominent person associated with a grading business is not necessarily the person who graded a particular card. For example, a company founder, price-guide author, or public spokesperson should not be assumed to have personally examined every item submitted to the service.
What do sports card grading companies evaluate?
A grading service examines a card’s physical condition and may assess whether it is genuine or has been altered. The exact criteria and grading methods vary by company, but visible condition is central to the result.
- Centering: How evenly the printed design sits within the card’s borders.
- Corners: Whether the points are sharp or show rounding, wear, or damage.
- Edges: Whether the borders have chips, roughness, or other flaws.
- Surface: Whether the card has scratches, print defects, stains, creases, or other marks.
- Authenticity and alteration: Whether the card appears genuine and has not been changed in a way that affects its originality.
A numerical grade summarizes the service’s opinion of the card’s condition under its rules. It is not a promise that every collector will agree with the result, nor does it guarantee a sale price. A card’s value also depends on its player, set, scarcity, demand, and sales market.
How the major grading companies compare
There is no single best grader for every card. Collectors often weigh buyer familiarity, the card’s age and type, the company’s label, available services, and submission cost. Service details can change, so review the company’s current submission instructions before sending a card.
| Grading company | What it is known for | Best for |
|---|---|---|
| PSA | A widely recognized name across many sports-card categories. | Collectors who value broad market familiarity and resale recognition. |
| SGC | A long-running grading service used for vintage and modern cards. | Collectors who prefer its presentation or want another established grading option. |
| Beckett Grading Services (BGS) | Known among collectors for detailed grading formats, including subgrades on some service options. | Collectors who want to compare specific condition categories where those options are available. |
| CGC Cards | A grading service that handles sports cards as well as other collectible categories. | Collectors who want to consider a service with experience across multiple types of collectibles. |
These descriptions are general, not promises about the grade a card will receive or the price it will bring. A label that attracts one buyer may matter less to another. If you are grading for a future sale, check recent sales of comparable cards in holders from the services you are considering.
How does the sports card grading process work?
Each company sets its own intake and examination procedures, but a typical submission follows these steps:
- Choose the service. Compare the company’s current options, fees, stated processing expectations, and submission rules. Confirm that it accepts your card and the service matches your goal.
- Prepare the card carefully. Follow the grader’s packaging instructions. Use a clean, appropriately sized sleeve and protective holder if required. Avoid touching the surface or forcing the card into a tight sleeve.
- Submit the order. Complete the required paperwork and identify each card correctly. Pack the shipment securely and use the shipping method and insurance that suit the card’s value.
- Wait for examination. Staff inspect the card under the company’s process. The service may assess condition, authenticity, or both, depending on the submission and its policies.
- Review the returned holder and label. Check that the card details and grade are recorded correctly. Keep the submission paperwork and any service documentation with your collection records.
Sending in a card does not guarantee a high grade, a particular turnaround, or a higher selling price. The company’s stated service terms explain what the submission includes and how it handles problems such as an authenticity concern.
Does the same card get the same grade from every company?
No. Different companies can assign different grades to the same card because their standards, procedures, and judgments may vary. Even within one service, close calls can involve subjective decisions about flaws such as centering, surface marks, or edge wear.
A grade is best understood as one company’s assessment under its grading system. It is not a universal measurement that every other service must match. This is why collectors sometimes see different grades on the same card after separate submissions.
Technology can also play a role in some grading workflows, but that does not mean every company grades cards in the same way. Check the service’s own description if you need to know whether a particular process uses imaging, automated tools, human review, or a combination. Do not assume that a tool or a label replaces the company’s stated grading standards.
How to choose a grader for your card
Start with your reason for grading. A card you want to protect for your collection may call for a different choice than one you plan to sell. Then weigh the card’s likely value against the total cost and practical risks of submission.
- For resale: Look at recent sales of similar cards in holders from each company. Compare like with like, including the card, grade, and grading label.
- For a personal collection: Consider the holder’s appearance, the service’s process, and how you want the card displayed or stored.
- For older or unusual cards: Confirm that the grader accepts the item and can identify its issue, variation, or printing correctly.
- For a potentially valuable card: Read the submission terms, shipping requirements, and coverage details before mailing it.
Do not choose a company based only on a friend’s experience or a single online sale. Submission options, fees, and buyer preferences can change. Make the decision using current information about your specific card and your intended use for it.
Common mistakes to avoid before submitting
Assuming a grade guarantees value
A graded card can be easier to identify, store, and compare with other examples, but a slab does not guarantee profit or a buyer. Estimate value from comparable sales, and include grading and shipping costs in your decision.
Cleaning or altering the card
Trying to improve a card with cleaning products, trimming, pressing, or other changes can damage it or affect how a grading service evaluates it. If you are unsure whether a mark is dirt or part of the original surface, do not try to remove it before submission.
Ignoring the card’s raw condition
A card’s player popularity does not erase flaws. Inspect the corners, edges, centering, and surface under good light before paying for grading. A realistic condition check can help you avoid submitting a card whose likely grade does not justify the expense.
Mixing up the company and the individual grader
The company name identifies the service behind the grade; it does not tell you which employee handled the card. Avoid treating a founder’s reputation or a specific grader’s supposed identity as proof of how a particular card was evaluated.
The short answer to who graded sports cards is that third-party grading services such as PSA, SGC, Beckett, and CGC assess and holder them. The company named on the slab is the clearest way to identify the service behind a card’s grade, while the individual grader is generally not named.
Before submitting a card, compare recent sales, check the service’s current rules, and inspect the card honestly for flaws. That simple check can help you choose a grader for the right reason and avoid spending more than the card and your goals warrant.
