Is My Card Worth Grading? A 5-Step Check With Worked Examples
Is my card worth grading? Usually only if two things are true: the graded copy sells for far more than the raw copy, and your card can realistically earn that grade. Everything else is arithmetic. The fee, shipping and insurance are certain. The grade is a guess. This guide shows how to turn that guess into a number before you spend anything.
You'll get a five-step check, a simple formula, and five worked examples. In one of them, the same card flips from "grade it" to "don't" because of a single centering reading.
Quick answer
Grade a card when all of these are true:
- The price gap between the raw card and the grade you can realistically get is several times your total grading cost.
- The front centering is inside the limit for the grade you're counting on.
- Corners, edges and surface hold up under a bright light.
- Your expected graded value, weighted by honest odds, beats the raw value plus the cost of grading.
If any of these fails, selling raw is usually the better move. Keep the card for yourself and the math changes, because protection and authentication count for something too.
The 5-step check
Step 1: Find the real price gap
Open the sold listings (not the asking prices) for your exact card, raw and graded. Note three prices: raw, a grade 9 copy and a grade 10 copy. The gap between raw and graded is the only reason to grade at all. If a 9 sells for only a few dollars more than raw, the fee can't pay for itself.
Step 2: Add up your total cost
Grading cost isn't just the fee. Add:
- The grading fee for your service level
- Shipping to the grader and back
- Insurance on the shipment
- Your marketplace's selling fee, if you plan to sell
- The raw value of the card, because that money is tied up for weeks
Fees change, so check the grader's current price list. For the examples below, we'll use a round $45 all-in per card for fee, shipping and insurance. That's an illustration, not a quote.
Step 3: Check the centering
Centering is the flaw you can measure at home, and it decides the top grades before anything else. For PSA, the published standards (approximately) allow 55/45 on the front for a 10, 60/40 for a 9 and 65/35 for an 8. If your front is 62/38, a 9 is out and the best realistic result is an 8. Our guide to how to measure card centering has the formula, every grader's limits and six worked examples.
Step 4: Inspect the rest
Hold the card under a bright light and tilt it. Look for:
- Whitening on the corners and along the edges
- Print lines, dents or scratches that show up only at an angle
- Gloss loss on holo patches
- Any bend, however small
Be harsh. Graders see the flaws you've stopped noticing. A good habit is to guess the grade, then drop it by one.
Step 5: Weigh the odds
Write down your honest chance of each grade. Then multiply each chance by what that grade sells for:
Expected value = (chance of 10 × price of 10) + (chance of 9 × price of 9) + (chance of 8 or lower × price of that grade)
Compare it with the total you're putting in:
Cost = raw value + grading cost
If the expected value isn't comfortably higher than the cost, don't submit. "Comfortably" means at least 15 to 20 percent higher, because your odds are estimates and estimates are usually optimistic.
5 worked examples
All prices here are made-up round numbers to show the method. Use your own sold-listing prices.
Example 1: The cheap modern holo
Raw value $20. A grade 10 sells for $90, a 9 for $30, anything lower for about $20. Centering is clean and you estimate 30% for a 10, 50% for a 9 and 20% lower.
Expected value: (0.30 × 90) + (0.50 × 30) + (0.20 × 20) = 27 + 15 + 4 = $46.
Cost: $20 raw + $45 grading = $65.
The expected value is $19 below the cost. Even a flawless-looking card loses money on average. Sell it raw.
Example 2: The same card idea at a higher price
Raw value $60. A 10 sells for $400, a 9 for $120, an 8 for $60. Front centering measures 52/48, corners are sharp, and you estimate 35% for a 10, 45% for a 9 and 20% for an 8.
Expected value: (0.35 × 400) + (0.45 × 120) + (0.20 × 60) = 140 + 54 + 12 = $206.
Cost: $60 + $45 = $105.
Expected value is about twice the cost. This is worth submitting.
Example 3: Same card, worse centering
Take the card from Example 2, but the front measures 62/38 left to right. That's outside PSA's approximate 60/40 limit for a 9, so a 10 and a 9 are both unlikely. Say 0% for a 10, 10% for a 9, 60% for an 8 and 30% for a 7 worth $40.
Expected value: (0.10 × 120) + (0.60 × 60) + (0.30 × 40) = 12 + 36 + 12 = $60.
Cost is still $105. A reading you could take at home in two minutes turned a good submission into a $45 loss on average. This is why centering comes before the price check on any card you're unsure about.
Example 4: How big does the 10 premium need to be?
You can shortcut the math for cards where only a 10 matters. The 10 premium (the 10 price minus the raw price) needs to beat your grading cost divided by your chance of a 10.
With a $45 cost and a 30% chance of a 10: 45 ÷ 0.30 = $150. The 10 must sell for at least $150 more than raw. With a 15% chance, the bar jumps to $300. This is why borderline cards, the ones with a small flaw and a 15% shot, almost never pay.
Example 5: The vintage card in rough shape
A vintage card with raw value $150 and obvious creasing won't get a high grade. Don't price it against a 10. Find sold prices for a grade 3 or 4 slab, since that's where it will land. If a slabbed 3 sells for $220, the gain is $70 minus $45 in costs, so $25. Thin. But authentication can make a vintage card much easier to sell and to trust, which sometimes matters more than the spread. This is the case where the math alone isn't the whole answer.
When to keep it raw
- The card is worth less than about twice the all-in grading cost.
- The graded and raw prices are nearly the same.
- Your front centering is outside the limit for the grade the profit depends on.
- You'd need a 10, and you can see flaws.
- You plan to keep it in a binder and just enjoy it. A slab is protection and a label, not an investment return.
Screen first, submit second
If you have a stack, don't run the full math on every card. Measure centering on all of them first, throw out the ones that fail, and only price the survivors. Suppose you have 20 candidate cards and 8 are worse than 60/40 on the front. Cutting those saves 8 × $45 = $360 in fees you'd have spent on cards with no shot at the top grades.
Our centering guide covers the rulers and the photo method. If you'd rather not do the math by hand, an app that straightens the photo and shows each grader's limits makes the screening pass much quicker.
Common mistakes
- Using asking prices. Only sold listings count.
- Counting on a 10. Plan for a 9 and treat a 10 as a bonus.
- Forgetting the raw value. It's money you can't use for weeks.
- Ignoring the back. A back that's too far off-center caps the grade too.
- Ignoring turnaround time. Grading takes weeks, and a hot market can cool before your card comes back.
- Trusting a predicted grade. Any tool, including a good one, gives an estimate. Only the grading company decides.
Frequently asked questions
Is it worth grading a card worth $20?
Rarely. With about $45 in total grading cost, the graded card has to sell for far above $65 just to break even. Only a card where a top grade carries a very large premium has a chance.
What centering do I need for a PSA 10?
Approximately 55/45 or better on the front and 75/25 or better on the back, based on PSA's published standards. Check the current figures before you submit, because graders can update them.
How do I know what grade my card will get?
You can't know for sure. Measure the centering, inspect corners, edges and surface, guess a grade, then lower the guess by one. Use that lower grade in your math.
Is grading worth it just for protection?
If you plan to keep the card, a slab protects it and authenticates it, and some people value that. Just don't count it as an investment return. Judge it as a purchase.
