Portal guides · Grading
"Is grading worth it?" is the wrong question, and it's why the answer you get is always vague. Worth it for whom, on which card, at what fee?
The right question is narrower and has an actual answer: is grading worth it for this specific card, right now? That's arithmetic, and it takes about two minutes.
This guide is the arithmetic. If you want the wider picture (what a grade measures, who to use, how to prep a submission), that's in our UK grading guide. This one is just the money.

Last checked: 23 July 2026. The worked examples use round illustrative numbers and a mid-range fee. The method doesn't change; the fees do, check current pricing before you submit.
The short answer
- The sum: (graded price × your realistic chance of that grade) − raw price − every cost. If that's not comfortably positive, don't send it.
- Price the 9, not the 10. Most cards don't come back a 10. Budgeting for the best case is the single most common way people lose money grading.
- The costs are bigger than the fee. Postage both ways, insurance, and your share of a bulk minimum routinely add 50 to 100% on top.
- Cheap tiers have minimums. If you have four cards worth grading, the cheap tier isn't available to you and your real price is the tier above.
- Grading for love is completely fine: just don't call it an investment while you're doing it.
The sum
Everything else in this guide is a footnote to this.
Write down five numbers. If you can't find one of them, that's your answer. A card with no comparable sales is a card you can't price the bet on.
Gain = graded price − raw price. That's the absolute ceiling. Then subtract every cost, and then discount the whole thing by the probability you actually hit that grade.
The five numbers
- Raw price: what your card has recently sold for ungraded. Sold, not asking.
- Graded price: what the same card sold for in the grade you're realistically expecting, from the grader you'd use.
- The fee: the tier you'd actually qualify for, not the cheapest one on the page.
- Postage and insurance: both directions, insured for the card's value.
- Your realistic grade: be honest. This is the number people fudge.
TipWhere to get the prices
Completed sales, not listings. eBay's sold filter, or a price tracker that sources from actual sales. An asking price tells you what an optimist wants, not what the market pays.
Three worked examples
Round numbers, chosen to show the shape of the decision.
These use a mid-range fee of £25 and £15 of postage and insurance both ways combined, to keep the arithmetic visible. Swap in real figures for your card and grader.
| Modern chase | High-end modern | Vintage holo | |
|---|---|---|---|
| Raw price | £40 | £220 | £300 |
| Price in a 10 | £95 | £600 | £1,100 |
| Price in a 9 | £45 | £260 | £520 |
| Fee + postage + insurance | −£40 | −£40 | −£40 |
| If it grades 10 | +£15 | +£340 | +£760 |
| If it grades 9 | −£35 | £0 | +£180 |
| Verdict | Don't | Only if it's genuinely clean | Send it |

Watch outLook at the modern chase column again
A card that more than doubles in a 10 still loses £35 if it comes back a 9. That's the trap. The headline gain looks great, the downside is invisible until it happens, and on a £40 card the fee is simply too large a share of the value.
As a rough working rule: below about £50 raw, grading rarely makes financial sense on modern cards unless the 10 multiple is extreme.
Price the 9, not the 10
The mental shift that saves the most money.
Everyone runs the sum with the 10 price. Almost nobody gets a 10 on every card.
You are placing a bet with a fixed stake (the fee and postage) on an uncertain outcome. The correct way to price a bet is by expected value: what each outcome is worth, weighted by how likely it is.
You don't need a precise probability. You need to be honest about which of three buckets your card sits in, and then run the sum on the likely outcome rather than the best one.
Be honest about the card
- Flawless out of the pack, dead-centred, sharp corners, clean under angled light: you can price toward the 10.
- Looks great but slightly off-centre, or one soft corner: price the 9. Centering is the flaw that caps the most grades.
- Any visible whitening, print line or surface mark: price the 8, and probably don't send it.
Commonly said"Japanese cards get 10s much more often, so they're always worth grading"
You'll see very specific figures for this, 15 to 20% versus 8 to 12%, that sort of thing. Chase the citations and they lead to other blogs. No grading company publishes grade-distribution data by language, and no manufacturer publishes centering tolerances.
What's fair to say: Japanese cards have a strong reputation for cleaner centering and fewer print defects, which is why people favour them for grading. Treat that as a reason to inspect your card carefully, not as a licence to skip the sum.
Portal takeIf you'd feel disappointed rather than fine about a 9, you're pricing the bet emotionally. That's the moment to put the card back in the binder.
When it's clearly worth it
The sum will tell you in most cases, but a few situations are reliably worth it and don't need much deliberation.
- Genuine vintage in strong condition. The graded premium on old cards is large and the supply of clean copies only shrinks.
- High-value modern chase cards that look flawless. The absolute gain is big enough to absorb the fee and a bit of grade risk.
- Cards you intend to sell to strangers. A slab removes the buyer's need to trust your description, that's worth real money on its own.
- Cards you want to keep forever. A slab is the best long-term storage that exists. If that's the reason, the resale maths simply doesn't apply.
- Anything where authenticity might be questioned. The certification is the point, not the number.
When the answer is no
And the situations where people most often talk themselves into it anyway.
- Cheap modern cards. The fee is too large a share of the value. Almost always a loss.
- Cards with a visible flaw. You already know the grade won't be a 10. The sum is already answered.
- Bulk you're grading "to see what happens". That's an expensive lottery ticket with a months-long wait.
- Cards with no comparable sales. If you can't price the outcome, you can't price the bet.
- Hoping a slab creates demand. Grading certifies condition. It cannot make a card desirable that wasn't.
Portal takeThe expensive mistake isn't grading the wrong card. It's grading twenty of them at once because the bulk tier looked cheap.
Questions people actually ask
Is grading Pokemon cards worth it?
For a specific card, yes if the graded price minus the raw price comfortably exceeds the fee, postage both ways and insurance, and if the card realistically achieves the grade you priced. For most modern cards under about £50 raw, it isn't worth it. For genuine vintage in strong condition and high-value modern chase cards, it usually is.
How do I work out if a card is worth grading?
Find the recent sold price raw, and the sold price in the grade you realistically expect. Subtract the grading fee, insured postage both ways, and your share of any bulk minimum. Then check the result still works if the card comes back a 9 rather than a 10. If it doesn't, don't send it.
What is the minimum value card worth grading?
There's no fixed threshold because it depends on the fee and the multiple between raw and graded prices. As a rough working rule, modern cards under about £50 raw rarely justify grading unless the 10 commands an unusually large premium.
Is it worth grading a card that might only get a 9?
Sometimes, on high-value vintage a 9 can still be worth well above raw. On modern cards a 9 frequently sells close to raw price, which means the fee is a straight loss. Always run the sum on the 9 outcome before deciding.
How much does it cost to grade a card in total?
More than the advertised fee. Add insured postage in both directions, your share of any bulk minimum, possible customs charges if the grader is overseas, and supplies. On cheaper tiers these extras routinely equal or exceed the grading fee itself.
Should I grade cards in bulk to save money?
Bulk tiers lower the per-card fee and spread return postage, which genuinely helps, but only if every card in the batch passes the sum on its own. Padding a submission to reach a minimum with cards that don't justify grading turns a discount into a larger loss.
Does grading increase a card's value?
Grading certifies condition and removes the buyer's need to trust your description, which is where the premium comes from. It cannot create demand for a card nobody wants, and a low grade can confirm a card is worth less than an optimistic raw listing suggested.
Grading is worth it more often than the sceptics say and far less often than the excitement suggests. The gap between those two positions is just arithmetic that nobody bothers to do.
Two minutes, five numbers, priced on the 9 rather than the 10. That's the whole method.
And if the answer comes out negative but you want to grade it anyway because you love the card, that's a completely good reason. Just call it what it is.
