Which grading company is best for UK sellers?

PSA usually commands the highest resale price and recognition, so it suits high-value cards. CGC is a strong alternative with well-regarded slabs. ACE is UK-based, which means no international postage or customs and fast domestic turnaround, often the practical choice for mid-value cards.

Is ACE grading recognised?

ACE is a UK grading company whose recognition is growing, especially with UK buyers. For the highest resale on premium cards, PSA is still the safest for value; for domestic sales and convenience, ACE is increasingly popular.

Is it worth grading Pokémon cards in the UK?

Only when the graded price comfortably beats the raw price plus the grading and postage cost, and mainly on genuinely near-mint high-value cards. Check graded sold comps before you commit, most cards are worth more sold raw.

PSA vs CGC vs ACE: which grading company (UK)

For UK sellers the choice comes down to four things: how much the grade lifts resale, what it costs, how long it takes, and the postage and customs of getting cards there and back. Here's how the three main options compare, and how to decide per card, not by habit.

Quick take

PSA: the most recognised globally and usually the strongest resale premium, so it earns its place on high-value cards.
CGC: well-regarded slabs and a solid alternative, often competitive on cost and turnaround.
ACE: UK-based, so no international postage or customs risk and fast domestic turnaround; recognition is growing with UK buyers.

PSA

PSA is the name most buyers know, and PSA-graded cards typically sell for the most, especially at grade 9 and 10. The trade-offs for a UK seller are cost and logistics: submissions historically route through a longer pipeline, and sending high-value cards abroad carries postage and customs risk. Best reserved for cards where the extra resale clearly covers it.

CGC

CGC has a strong reputation in trading cards and produces slabs many collectors rate highly. For a lot of cards it lands between PSA and ACE on resale, and it can be competitive on price and speed. A sensible middle option when you want a widely respected slab without the top PSA premium or wait.

ACE Grading

ACE is a UK-based grader, which changes the maths for domestic sellers: no overseas shipping, no customs, and faster turnaround because the card never leaves the country. Its recognition is still growing, so the resale premium can be lower than PSA on blue-chip cards, but for mid-value cards sold to UK buyers, the convenience and lower total cost often win.

Cost, turnaround and postage

Grading prices and turnaround times change often and vary by service tier and card value, so always check the current rates before you commit. The number that actually matters is the all-in cost: grading fee plus insured postage both ways (and any customs when grading abroad). A £15 raw card rarely justifies £30 of grading and postage. The grading ROI calculator works out the uplift and break-even for a specific card.

Does grading lift the price?

Sometimes a lot, usually not enough. Grading pays when the graded sold price comfortably beats the raw price plus your all-in cost, and that mostly happens on genuinely near-mint, higher-value cards. Before you send anything, read the sold comps for that exact card in both raw and graded form, and compare the gap to your cost.

So which should you use?

High-value, near-mint card you're confident will grade well, PSA for maximum resale. Want a respected slab with less cost or wait, CGC. Mid-value card sold mainly to UK buyers, or you value speed and no customs, ACE. The right answer is per card, driven by the graded premium versus your all-in cost.

Curio shows a graded price signal (PSA and CGC asking prices) next to the raw price for each card, so you can see the grade premium before you pay to grade, part of grading and condition and pricing your cards.
