Four things decide a grade. We measure all four.
Every card goes through a machine we built that takes over 800 measurements. Then a person checks it by hand under calibrated light to make sure it's genuine. No AI, and no guessing.

Questions collectors ask
How is CALIBRE different from PSA or CGC?
PSA and CGC graders look at your card and decide, against their written standards - and you get the grade, not the measurements behind it. CALIBRE measures your card and shows you the measurements and photos behind the grade in a public report - so you can check it yourself, not just trust it. £25 a card - return postage always on us, back within 7 days of arrival.
Will a CALIBRE slab sell for more?
Straight answer: on big chase cards, a PSA 10 still sells for the most - PSA has decades of sales history and we're new. What a CALIBRE slab gives your buyer is proof: they can look up every measurement and photo behind the grade from the number on the label. Selling a big card abroad? PSA is still the safer bet. Want a quick, honest grade on a card you're keeping, or selling in the UK? That's what we're for.
Is my card checked for authenticity?
Yes. Every card is checked by hand under calibrated lighting before we grade it.
Is a measured grade consistent?
Every card is measured against the same standards, so your grade doesn't depend on who's working that day. Your report shows the measurements behind your grade, with photos. If something looks wrong, you'll be able to see it.
What if I disagree with a grade?
Tell us within 14 days of getting your report. If we really did make a mistake, we'll measure the card again for free and show you exactly what we found. Because it's a measurement and not someone's opinion, we can show you exactly why.
Is my card safe with you?
It's sealed in a case you'd know if anyone opened, and posted back tracked within 7 days of arriving, not sitting in a vault for months. Every card is insured with XCover on its way back to you, at the value you give it when you order: up to £1,000 free, or its full value if you choose full-value cover. Over £2,500 in one order? Contact us first.
