A slab is reassuring at first glance. Sealed case, crisp label, certification number: everything says a professional has examined this card, graded it and locked it away. That trust is deserved in the vast majority of cases. It is also exactly what fraudsters try to exploit. The good news: a handful of simple habits, none taking more than five minutes, will filter out almost every fake in circulation. This guide walks through them, from the essential to the situational.
Why counterfeiters target slabs
Selling a fake raw card means fooling a buyer who will inspect it from every angle. Selling a fake slab is a different game: the case does the "certifying" on the buyer's behalf, and vigilance drops accordingly. Why scrutinise the print texture of a card that PSA, Beckett or CGC has already signed off on?
Then there is the money. A high-grade card routinely sells for hundreds of euros, sometimes thousands — enough to justify a level of effort no one would invest in faking a twenty-euro card. The higher the market value, the more profitable the fake, and the more those five minutes of checking are worth your time.
The three main families of fraud
The fully counterfeit case
The crudest version: a case imitated from scratch, label included, wrapped around a counterfeit card or a reprint. These often give themselves away through the plastic quality, sloppy seams, or a label whose font and alignment look off. But "often" is not "always", and the quality improves every year. Do not rely on your eye alone.
A redone label on a genuine case
More insidious: a real case, opened and resealed, with a modified or replaced label — an inflated grade, or an ordinary card swapped for a copy of an expensive one. Because the case itself is authentic, the feel of the plastic will not warn you. What gives it away are signs of tampering along the edges and seams, and above all a mismatch with the grader's database.
The "cloned cert"
The sneakiest of the three. The fraudster copies the certification number from a real slab — visible in any public listing — onto a fake case holding a copy. Look the number up and everything checks out: it exists, the card matches, the grade matches. There is a counter, though, and it is simple: do not just confirm the number exists. Compare in detail. Which brings us to the core reflex.
Reflex number one: the grader's official database
Every major grading company offers free, public online cert verification. You type in the number printed on the label, and the database returns the official record: card, set, year, grade, and in most cases photos of the slab taken at grading time.
This is the decisive moment of the whole check, so do not rush it:
- The number must exist in the database. If it returns nothing, walk away.
- The record must match exactly: same card, same set, same language, same grade. A record describing a different card is a deal-breaker.
- Compare photo by photo when the grader provides images. Centering, holo pattern, any visible flaw: the card in the listing must be the same physical copy as the one in the official record — not merely the same card at the same grade. This is the specific step that defeats the cloned cert.

Red flags before you buy
None of these proves fraud on its own. Two or three together should make you move on.
- A price well below market with no explanation. A sought-after card has a known, checkable market price. A 40% discount "because I need to sell fast" is the oldest bait there is.
- Blurry, cropped or stolen photos. An honest seller of an 800-euro card knows how to photograph it. Shots that conveniently hide the label or the corners of the case are not an accident.
- A rushed seller who refuses extra photos. Asking for one more angle is a routine request between collectors. Refusing it is not.
- Label inconsistencies: an unusual font, misaligned text, a hologram missing or different from recent slabs by the same grader. Compare against examples you know are genuine.
Good habits for buying online
For a private, peer-to-peer purchase, three habits change everything.
- Ask for a personalised photo: the slab next to a piece of paper with your username and today's date, handwritten. Impossible to produce with stolen pictures.
- Run a reverse image search. A few seconds is enough to discover that the listing photos come from another listing, sometimes posted in another country.
- Pay with recourse. A platform's buyer protection, a credit card: methods that let you dispute the transaction. Never a bank transfer or a "friends and family" payment, which amounts to waiving every recourse you have — and a seller who insists on one is telling you something.
If you are buying across a border, add customs and VAT to the equation: our guide to buying graded cards in Europe covers both.
Suspect a fake after the purchase?
Do not panic: there is a process. Document everything first — photos of the slab from every angle, a screenshot of the listing, your messages with the seller. Then contact the platform and open a dispute within the allowed window; this is where your choice of payment method pays off. Report the listing to protect the next buyer, and notify the grading company involved: graders track these reports closely. If you have suffered a genuine loss, filing a police report remains an option; counterfeiting is a criminal offence across Europe.
Above all, do not put the slab back into circulation. Reselling a fake, even in good faith, exposes you in turn.
What a specialised marketplace changes
Everything above describes peer-to-peer buying, where verification rests entirely on you. A specialised marketplace moves that work upstream — which is the principle behind Graded Market. The certification number is checked when a listing goes live and every listing is tied to one specific slab; sellers are vetted before they can sell; payment sits in escrow until the delivery matches the listing. The risk never drops to zero — no system is perfect — but it changes scale. You can browse the listings and save your energy for the only question that actually matters: this card, at this price — do you want it?
The pre-purchase checklist
- Verify the certification number in the grader's official database.
- Compare the record in detail: card, set, language, grade — and photo by photo where available.
- Check the price against recent sales of the same card at the same grade.
- Ask for a personalised photo (username and date on paper).
- Reverse-search the listing images.
- Pay only through a method that offers recourse.
Six lines, five minutes. That is the price of peace of mind — and it is far lower than the price of a fake.
