This question comes up constantly in collector groups, and the answer hasn't changed much: it depends. But "it depends" isn't particularly helpful, so let's get specific about when grading makes financial sense and when it doesn't.
Grading works best when you've got a card that's already worth a decent amount raw and you're confident it'll score well. The sweet spot is cards worth £30 or more in raw condition with a realistic chance of getting a 9 or 10.
Here's a real example. A raw Moonbreon (Umbreon V Alternate Art from Evolving Skies) might sell for around £150. A graded 10 of the same card regularly sells for £400 to £500. Even after grading fees and postage, that's a solid return.
On the flip side, a raw card worth £5 that comes back as a 9 might sell for £8 to £10. After the grading fee, you've lost money. The grade has to create enough of a price increase to cover your costs and then some.
Modern Pokémon cards are printed in enormous quantities. That means the population of graded 10s is high and climbing. When there are thousands of PSA 10s of a particular card floating around, the premium for a graded copy shrinks.
This is less of an issue with UK grading companies that are newer to the market. Their populations are still low across the board, which can actually work in your favour. A graded 10 from a newer company with a low population count can carry a decent premium simply because there aren't many of them.
Older cards from Base Set, Jungle, Fossil, Team Rocket, and the Neo series almost always benefit from grading. These cards are 20+ years old. Finding one in genuinely mint condition is unusual, so high grades carry serious premiums.
A raw Base Set Charizard (unlimited) in good nick might sell for £200 to £300. A PSA 9 of the same card goes for £500 to £800. A PSA 10 can fetch £2,000 or more. The rarity of high-grade vintage cards drives prices up considerably.
Not everyone grades cards to flip them. Some collectors grade cards they plan to keep forever. There's nothing wrong with that. A graded card in a proper case is protected from handling damage, humidity, and UV light. It's the best way to preserve a card long-term.
If you've got sentimental cards, cards you pulled yourself, or cards from your childhood collection that you'd never sell, grading them is a reasonable way to make sure they stay in the condition they're in now.
Grading is worth it if you're selective about what you submit. Don't grade everything. Grade cards where the maths works out or cards you want preserved properly. The UK market has matured enough that you've got affordable options without needing to ship overseas.
