PSA Grading: How the Whole Process Works

PSA grading is a paid service in which a third-party company inspects a trading card, confirms it is genuine, assigns it a condition grade on a 1 to 10 scale, and seals it in a tamper-evident plastic holder called a slab. The slab carries a label with the grade and a certification number you can look up online. You pay a per-card fee, mail the card in, and wait. The wait is currently measured in months, not weeks, and the price depends on which service level you pick and what the card is worth. This guide walks through the whole path from raw card to slab, what the graders are looking at, what each number means, and how to decide whether a given card is worth sending.

What PSA actually does

PSA stands for Professional Sports Authenticator, a name that dates to its start in sports cards. Today it grades Pokemon, Magic, basketball, baseball, football and many other kinds of cards. A submission goes through two jobs that are easy to blur together.

The first job is authentication. Someone confirms the card is real and has not been trimmed, recolored or otherwise altered. The second job is grading, which means measuring the card's condition against a written standard and putting a number on it. A card that is genuine but altered cannot receive a numerical grade. PSA marks those cards "Authentic" instead, with no number, and they sell at a steep discount to a graded copy.

After the card is graded it is sealed in the slab, and the label is printed. From that point the grade is part of the object. Buyers do not have to judge the corners themselves, which is why graded cards usually change hands faster and with fewer disputes than raw ones.

The 1 to 10 scale

PSA publishes a named grade for each whole number. The names below are the ones the hobby uses everywhere.

The top of the scale is where the money is, and it is also where the standard is strictest. A 10 is not "perfect" in the sense of being flawless under a microscope. It means the card has no flaw the grader will call disqualifying, and many 9s look identical to 10s at arm's length.

### Half grades

PSA also awards half grades. They run from 1.5 through 8.5, and they have been part of the system since February 1, 2008. There is no 9.5. PSA's stated reason was that it already had a Mint 9 and a Gem Mint 10 and did not need a third Mint grade. A half grade signals an exceptional example within a whole-number grade, such as a card that is a strong 8 but not quite a 9. Half grades apply to single cards, not to sealed products.

What graders look at

Four categories decide the number, and a card is held to the level of its weakest one.

Centering. This is how evenly the artwork sits within the borders. Published summaries of PSA's standards put a 10 at roughly 55/45 or better on the front and 75/25 or better on the back, and a 9 at roughly 60/40 or better on the front and 90/10 or better on the back. Treat those figures as the commonly cited tolerances, not as a measuring rule. Centering is the single most common reason a clean-looking card misses a 10, and it is the one flaw you can check at home with a ruler or a simple overlay.

Corners. Sharp, square corners with no fraying, whitening or rounding. Whitening on a dark-bordered card shows up quickly and costs grades fast.

Edges. Clean edges with no chipping. Cards with dark or colored borders show chips more easily than cards with white borders.

Surface. The face and back of the card. Graders look for scratches, print lines, dents, staining, indentations, and loss of gloss. On holographic cards, surface scratches in the foil are the most common problem, and they can be invisible until you tilt the card under a light.

### Qualifiers

When a card meets the standard for a grade except for one named flaw, PSA can attach a qualifier. The common ones are:

• OC (Off Center): centering is worse than the standard for the grade.
• ST (Staining): staining beyond the standard for the grade.
• PD (Print Defect): a significant manufacturing print flaw.
• MK (Marks): writing, ink or pencil marks.
• MC (Miscut): a factory miscut.

A qualified card typically sells at a discount to the same grade without one, and many buyers avoid them. A card with no qualifier is sometimes written "NQ" in listings.

From raw card to slab, step by step

The sequence is the same whichever service level you choose.

1. Pick the cards. Raw value, condition and the likelihood of a high grade should all pass a filter before you spend anything. More on that below.

2. Create an account and choose a service level. PSA sells service levels that differ in price, turnaround and the maximum declared value of the card. Our companion guide, PSA Grading Cost: Every Tier Priced, lays out the current tiers. Whether a paid membership is required for a given tier has changed over time, so confirm it on PSA's own website before you start.

3. Fill out the submission form. You list each card with its year, set, card number and player or character, and you declare a value. The declared value matters. If a card is worth more than the maximum for the tier you chose, PSA can move it to a higher tier and charge the difference.

4. Protect the cards. The standard approach is a soft penny sleeve, then a semi-rigid holder. PSA's published packing guidance asks submitters not to send cards in rigid top loaders, and badly packed submissions can be returned or charged a handling fee. Read the current packing instructions before you box anything.

5. Ship it insured and tracked. Use a carrier with tracking and a signature requirement. The insurance should match the declared value. Under-declaring creates a problem if the package is lost, and over-declaring can push a card into a higher tier.

6. Wait for intake, then for grading. Turnaround estimates generally start when PSA logs the submission into its system, not on the day you mail it. Add shipping time on both ends. In 2026 PSA has had a very large backlog, and its lower-cost tiers have been paused, so waits have been long. Check the status of the order through your account.

7. Receive the slab. The card comes back sealed, graded and labeled.

Reading the label and verifying a cert

A PSA label shows the card's year and set, the card name or player, the card number, the grade with its name, and a certification number, often called a cert number. Newer labels also carry a QR code. The cert number is typed into PSA's cert verification page on its website, which returns the card description and grade PSA has on record for that number.

Always do the lookup before buying a slab you did not watch being graded. Two outcomes are warning signs. If the number returns no record, the slab may be counterfeit. If it returns a different card than the one in the holder, the card may have been swapped. PSA itself notes that a matching record does not remove all risk, because counterfeiters have copied real cert numbers onto fake labels. The lookup is a necessary check, not a sufficient one. It works best alongside a close look at the slab itself and a seller you can ask questions of.

Is grading worth it

Grading is not automatically a good idea. You pay the fee, the shipping both ways and the insurance, and you accept the risk that the grade comes back lower than you hoped. Three questions settle most cases.

What is a raw copy worth, and what is the same card worth at each grade? Look at completed sales, not asking prices. Our guide How Much Are Pokemon Cards Worth? covers how to read those numbers. If a 10 sells for four times the raw price and a 9 sells for barely more, the whole decision rides on getting that 10.

What is a lower grade worth? For many modern cards, an 8 or below sells for little more than the raw card, and sometimes less. For older or scarcer cards, even mid-grades carry real value, because few copies survive in good condition.

What does it cost all in? The grading fee is only part of it. Add shipping to PSA, return shipping, insurance and supplies, and count the months your money and card are tied up. A simple break-even test is that the gain from the grade you realistically expect must exceed the total cost, with room to spare for the chance that the grade comes in lower.

Several general rules hold up across the hobby:

• Cards that are worth little raw rarely justify a fee that can be larger than their value.
• Condition you can see matters. If you see whitening on the corners or scratches in the holo under a lamp, assume the grader will see them too.
• Centering you can measure matters. A card that is visibly off-center will rarely get a 10, however clean the rest looks.
• Older and scarcer cards tend to justify grading at lower raw values than modern, heavily printed ones, because the supply of high grades is small.
• If you plan to hold the card, grading can also protect it. If you plan to sell it quickly, the months of waiting may cost you the market you wanted.

Seeing a card before you commit

Slabbed or raw, the best check on condition is seeing the actual card. Live selling helps here because you can ask the seller to turn the card under the light, show the corners and the back, and read out the cert number on camera so you can look it up before you bid. On ShopBidz, Houseofcards859, a card seller from Wantagh, New York, and BuzzTCG, from Maryville, Tennessee, who sells trading cards and sports cards, are two sellers you can watch live. If you are weighing a raw card against a slabbed one, seeing the card move on camera and asking for the angles you want costs nothing. Our guides Where to Sell Pokemon Cards and Where to Sell Sports Cards cover the selling side.

Common mistakes

• Sending cards that are not ready. Dust, fingerprints and fibers on the surface can cost a grade. Handle cards by the edges and keep them out of the open air until they are packed.
• Declaring the wrong value. An honest declared value avoids upcharges and keeps insurance meaningful.
• Ignoring the backlog. Check the current turnaround before you decide, particularly if you need the cards back by a date.
• Expecting a 10 on every clean-looking card. Even excellent cards often come back a 9 or lower because of centering or a tiny surface mark.
• Buying a slab on the label alone. Verify the cert, inspect the holder, and buy from someone you can ask questions.

Bottom line

PSA grading turns a card's condition into a number on a 1 to 10 scale, with half grades up to 8.5, and seals the card in a labeled slab you can verify by cert number. The process is simple to follow and slow to finish: choose a service level, declare an honest value, pack the cards the way PSA asks, ship insured, and wait. Whether it pays depends on the gap between what the card sells for raw and what it sells for at the grade you can realistically expect, minus all the costs. Check that gap with real sold prices before you submit, verify any slab you buy, and prefer to see the card in action before you pay.
