ACE 10 vs PSA 10: What UK Collectors Need to Know

By Ben Slack, co-founder, Card & Ink · Last updated 17 August 2026. You've found the card you want, and there are two of them in front of you. One sits in an ACE 10 slab, one in a PSA 10. Same card, same set, same number on the label, and the prices aren't close. This guide explains what the two tens mean, why the market pays differently for them, and which is the right buy for you.

The short version

• Both are real grades, but they aren't the same currency. Each company grades to its own internal standards, and no grade transfers between companies.
• PSA generally carries the bigger resale premium, especially on vintage and high-value cards, off decades of track record and deep population data.
• ACE Grading is UK-based, takes submissions domestically and prices in pounds, so there's no customs step.
• "Perfect Subgrades" means top marks across centring, corners, edges and surface. Treat it as useful information, not a guaranteed price uplift.
• The fee has to make sense against the card. On a £20 card, a £79.99 grading fee never makes sense, whoever is charging it.
• Buy the card, then the slab. Check the label, holder and photography before you look at the logo.

Who ACE Grading actually is

ACE Grading is a UK grading company. Cards are submitted domestically, fees are paid in pounds, and there's no cross-border leg to manage. It's established enough to have its own Wikipedia entry, and it has become a common sight on UK listings and at UK shows.

PSA is the comparison point: the long-established US company, and by some distance the most recognised grading brand in the hobby. That recognition has historically come with friction here, as submissions meant international postage, customs handling and a longer round trip. PSA has announced a UK Receiving Center opening later in 2026, which should remove much of that. Until it's operating, the practical gap between submitting to ACE and to PSA from a UK address is real.

None of this makes either company better. It makes them different propositions, and which suits you depends on whether you're buying, holding or selling.

Why the same "10" carries different money

There's no shared industry standard for grading. Each company publishes its own criteria and applies its own internal scale. Comparing an ACE 10 with a PSA 10 isn't two measurements on the same ruler; it's two separate opinions that happen to be expressed as the same number. The price difference comes down to three things.

• Track record. The market has priced PSA slabs against each other for decades and has a settled sense of what a PSA 10 is worth. That confidence has value.
• Population reports. A population report is a public census of everything a company has graded: how many copies of a card it has seen, and how many landed at each grade. If 4,000 copies have been graded and only a handful came back as 10s, that scarcity is visible to everyone and gets priced in. A grade without comparable public data is harder to price confidently, so buyers pay less.
• Liquidity. At the top end, buyers want the slab they know they can resell internationally, which widens the premium.

The gap has narrowed here. As ACE and CGC build domestic track records, the discount on a non-PSA slab is less severe than it was, and on modern cards it's often modest. It hasn't closed, and on vintage it remains significant.

Worth noting: niche UK market trackers have reported the singles market cooling since spring 2026, with modern Mega Evolution-era chase cards correcting notably off their spring peaks through the summer. Any premium you pay today should be one you'd still be comfortable with in a flatter market.

Subgrades and "Perfect Subgrades", explained properly

An overall grade is one number summarising the whole card. Subgrades break that down into the individual criteria graders assess:

• Centring: how evenly the border frames the artwork, front and back.
• Corners: sharpness, with any whitening, softness or bluntness noted.
• Edges: chipping, nicks and whitening along the four sides.
• Surface: print lines, scratches, scuffs, dimples and holo scratching.

A card can reach a high overall grade while being noticeably weaker in one area. Subgrades show you where, without you having to interrogate every millimetre of a photo yourself.

Many ACE 10 cards on the UK market carry a "Perfect Subgrades" designation, meaning top marks across all four criteria rather than a strong overall grade carried by three good areas and one average one. For a condition-led collector that's meaningful, and a single-number label doesn't give it to you. Most PSA Pokémon slabs show one overall grade rather than a breakdown.

Be measured about resale, though. It tells you something real about the card, but it doesn't automatically convert into a higher price, and the market for subgraded modern cards is still young. Value it as better information at the point of purchase.

When ACE makes more sense, and when PSA does

Situation	Usually the better fit	Why
Vintage or high-value cards	PSA	Deepest population data, strongest resale liquidity
Long-term hold where resale is the point	PSA	Widest buyer recognition when you sell
Modern cards of moderate value	ACE	The fee has a realistic chance of being justified
You want it back quickly, in GBP	ACE	Fast tiers, no customs leg from a UK address
You want condition detail on the label	ACE	Subgrades shown, not summarised into one number

Cost is the part people skip. Published per-card rates as of mid-2026 — always check the grader's own site, as tiers change:

• PSA (USD, plus international shipping and customs for UK submitters until the UK Receiving Center opens): Regular $79.99, around 40–50 business days; Express $149, around 20–30; Super Express $349, around 7–10; Walk-Through $599, around 5–7; premium tiers from roughly $999 upward.
• ACE Grading (GBP, UK submission): Core/Value £12–£15 for AceSelect members, around 75–95 business days; Basic £18, around 45; Standard £25, around 25; Premier £32, around 10; Ultra £60, around 5; Luxury £120, around 2 business days.
• CGC (GBP, UK operation, roughly 50-day turnaround across tiers): Bulk £16.80 for cards up to £400 with a 25-card minimum; Economy £19, up to £800; Standard £54, up to £2,500; Express £96, up to £8,000; WalkThrough £288, up to £80,000.

Run the sum before you commit. If the fee plus postage is a large share of what the graded card would fetch, it isn't a grading candidate. That arithmetic applies to every company here.

What to check on any slab before you buy

• Read the whole label. Year, set, card name, number and grade should all match the card you think you're buying. Reprints and alternate arts trip up more buyers than fakes do.
• Check the certification number. It should be legible and match the card in the holder.
• Look at the slab itself. Cracks, gaps at the seams, scuffing over the card, or signs a holder has been opened and resealed are reasons to walk away regardless of the grade.
• Insist on a photo of the actual card. A stock image tells you nothing about the item you'll receive. At Card & Ink we photograph the actual card, front and back, on every listing, so what you see is the exact slab posted to you.

If you're selling graded cards

Selling a slab is easier than selling a raw card, because the condition argument is already made for you. Your options are listing it yourself, an auction platform, or selling to a shop.

With us there are two routes. An outright sale means you keep 70% and get paid promptly once you accept our offer. Consignment means you keep 80%, with a 15p-per-card handling charge, and you cover postage both ways since anything unsold comes back to you. Consignment pays more but takes about a month.

The process is the same either way: send the cards in, we do a condition check, then we make an offer. We don't quote from photographs or give figures before we've physically seen the cards. Details are on our sell your cards page.

On grading: we don't currently offer a public grading service. We're building an invite-only service for collectors, and you can register your interest here.

FAQ

Is an ACE 10 the same as a PSA 10?

No. Each grading company grades to its own internal standards, and a grade from one does not transfer to another. Both represent that company's top grade for the card, but they are separate assessments and the market prices them separately.

Why does a PSA 10 usually cost more than an ACE 10?

Mostly track record and data. PSA has been grading for decades and publishes population reports showing how many copies of a card it has graded and at what grades, which gives buyers a clear picture of scarcity. That supports higher resale prices, particularly on vintage and high-value cards. The gap has narrowed in the UK but has not closed.

What does "Perfect Subgrades" mean on an ACE slab?

Subgrades are separate scores for the criteria a grader assesses: centring, corners, edges and surface. A Perfect Subgrades designation means the card scored top marks on all four, rather than reaching a high overall grade with one weaker area. It is useful transparency, but it does not automatically guarantee a higher resale price.

Is ACE grading worth it for modern Pokémon cards?

It can be, if the card's value justifies the fee. ACE takes UK submissions in pounds with no customs step and publishes fast tiers, which suits modern cards where speed and cost matter. The test is arithmetic rather than brand: if the fee and postage swallow a large share of what the graded card would sell for, it is not worth grading.

Can I have an ACE-graded card regraded by PSA?

Only by cracking it out of its holder and submitting it as a raw card, which removes the existing grade and the protection of the slab. There is no guarantee the new grade will match the old one, and you pay the full fee again either way. For most cards the cost and risk outweigh the potential uplift.

Does Card & Ink grade cards?

Not currently. We do not offer a public grading service. An invite-only service for collectors is in development, and you can register your interest on our site to hear when places become available.
