If you are new to trading card collecting, you have probably seen cards sealed inside hard plastic holders with a number displayed on the label. These are graded cards, and card grading has become an important part of the modern collecting hobby. But what is a graded card, exactly? What does the grade mean? How does card grading work, and how do you know whether a card is worth submitting?
Whether you collect baseball, basketball, football, hockey, soccer, or trading cards, understanding card grading can help you make better decisions when buying, selling, or protecting your collection.
What is a graded card?
A graded card is a trading card that has been professionally evaluated for authenticity and condition, assigned a grade according to a grading company’s standards, and usually sealed inside a protective holder called a slab. The grade, the card’s details, and a unique certification number are printed on a label at the top of the slab so that any buyer can verify it online in seconds.
What Does a Card Grade Mean?
A card grade is a standardized assessment of its condition, usually on a scale up to 10. Higher grades generally mean better centering, sharper corners, cleaner edges, and fewer surface flaws. While higher grades can increase desirability and value, price also depends on rarity, player popularity, demand, population, and market conditions.
Raw vs. Graded Cards
A raw card is simply a card that has not been professionally graded or encapsulated. A graded card has gone through a professional authentication and grading process and is protected inside a slab.
For example, you might own a raw rookie card that appears to be in excellent condition. You could keep it in a sleeve and holder, or you could submit it for grading. If it receives a strong grade, the graded version may appeal to collectors who prefer professionally authenticated and encapsulated cards.

What is card grading, in plain terms?
Card grading is a professional, independent assessment of a card’s authenticity and physical condition, expressed as a standardized number. Instead of a seller describing a card as “near mint” and a buyer disagreeing, a grading company gives both sides a shared reference point.
For ungraded cards and larger collections, card binders can offer another practical way to organize cards by player, team, set, or collection.
- Graded sports cards — baseball, basketball, football, hockey, soccer, and more. Sports card storage cases
- Graded trading cards (TCG) — Pokémon, Magic: The Gathering, Yu-Gi-Oh!, One Piece, Lorcana. TCG and non-sports card cases
- Non-sports cards — entertainment, comics-themed sets, and vintage novelty issues.

Why Do People Get Cards Graded?
Collectors typically grade cards for several reasons:
- Authentication: Helps establish whether a card is genuine.
- Condition: Provides a standardized assessment of the card’s condition.
- Protection: For additional protection and organization, collectors can also use dedicated card storage cases for their graded collections.
- Resale: A professionally graded card can be easier for buyers to evaluate.
- Organization: Slabs make valuable cards easier to identify and store, especially when paired with a dedicated graded card storage solution.
- Collecting: Some collectors enjoy building collections around specific grades, players, sets, or grading companies.
However, grading does not automatically increase a card’s value. The cost of grading, the card’s condition, demand, grade population, and the market for that particular card all affect whether grading makes financial sense.
What do card graders look at?
Graders evaluate four core condition factors: centering, corners, edges, and surface. Eye appeal and print quality also influence the final number, and a single weak area can hold back a card that is otherwise flawless.
Centering measures how evenly the image sits within the card’s borders, front and back. It is expressed as a ratio, such as 55/45, comparing the border widths on opposite sides. Each company publishes its own centering tolerances for each grade, and those tolerances have been revised over time — so check the official grading-standards page rather than a forum post or an old blog.
Graders check all four corners under magnification for rounding, fraying, dings, or softness. Corners take damage easily from shuffling, rubber bands, loose storage, and even careless sleeving.
Edges are inspected for chipping, nicks, rough factory cuts, and “whitening” — small flecks where the colored border has worn away to reveal the card stock underneath. Dark-bordered cards show edge wear most clearly.
Surface covers everything on the face and back of the card: scratches, print lines, print spots (“fish eyes”), dimples, indentations, stains, loss of gloss, and creases. Chrome and holographic finishes are especially unforgiving because light reveals every scuff.
How to get a card graded: step by step
Preparing a card for grading can be relatively quick, but the overall submission process may take days or months depending on the company, service level, shipping, and current submission volume.
- Research the card’s value. Search eBay “Sold” listings (not active asking prices) and tools like Card Ladder or PSA’s Auction Prices Realized. Note what raw copies and each grade actually sell for.
- Inspect it honestly. Use a bright LED lamp and a jeweler’s loupe or your phone’s zoom. Tilt the card under the light to catch scratches, print lines, and dents. Check the back, too — graders do.
- Measure centering. Compare the left/right and top/bottom borders. Centering requirements vary by grading company and grade, so collectors should review the current standards of the company they plan to use.
- Clean gently (only if needed). If necessary, remove loose dust carefully according to the grading company’s preparation guidelines. Avoid liquids, erasers, abrasives, or aggressive cleaning, as altering a card can affect its eligibility or grade.
- Pick a company and service level. Match the tier to the card’s expected graded value, not what you paid for it, to avoid upcharges.
- Sleeve it properly. Put the card in a fresh Premium sleeve, then a semi-rigid holder. Most graders prefer semi-rigids over Z loaders.
- Fill out the order online. Enter the year, set, card number, player, and declared value carefully. Mistakes slow down your order.
- Pack and ship securely. Sandwich the cards between cardboard, fill space so nothing shifts, and ship with tracking and insurance. Many graders also accept drop-offs at card shows and through authorized dealers.
- Track and verify. When your slabs arrive, check each label and look up every cert number online.
Common beginner mistakes to avoid
- Grading everything. Base cards of non-stars rarely justify today’s fees.
- Assuming a pack-fresh card is a 10. Factory flaws — print lines, rough cuts, off-centering — are extremely common in modern products.
- Using asking prices instead of sold prices to estimate value.
- Underdeclaring value to save money. It can trigger upcharges and leave you underinsured if something goes wrong.
- Cracking a slab to resubmit without a plan. Sometimes it works, but you can also get a lower grade and lose the original.
- Buying slabs without checking the cert. Fake labels and swapped cards exist.
- Ignoring turnaround time. If you need to sell before a player’s hype fades, a four-month wait matters.
How Much Does It Cost to Grade a Card?
Card grading costs vary by grading company, service level, card value, turnaround time, and additional services. Economy options are generally designed for lower-value submissions, while expedited services typically cost more. Shipping, insurance, and possible additional fees should also be included when calculating the total cost.
