How to Spot a Fake Graded Slab

Why isn't a cert-number lookup enough on its own?

Every major grader gives you a free, public way to verify a card by its certification number. PSA has its cert lookup at psacard.com/cert, Beckett (BGS) has a card lookup on beckett.com, and SGC has a cert-code lookup on its site. Enter the number printed on the label and the grader returns the card, the grade and — for most modern certs — reference photos. If nothing comes back, or the details don't match the slab, stop there.

The catch is that a working lookup does not prove the slab is genuine. PSA itself acknowledges that criminals counterfeit its grading inserts using real certification numbers scraped from public sources — old eBay sold listings, population reports, social posts. So a fake slab can carry a label whose number checks out perfectly. The lookup confirms that a number is real; it cannot confirm that the case, label and card in your hands are the ones that number belongs to. That's why the physical checks below matter just as much.

How do I physically inspect a slab?

Once the number checks out, examine the slab itself. You're looking for the manufacturing quality and security features that fakes struggle to reproduce, and for any sign the case has been opened and re-sealed to swap the card inside.

• Match the card to the cert photos: pull up the grader's images for that cert number and compare centering, print marks, surface scratches and any flaws. A genuine slab will match its own photos; a fake with a borrowed number usually won't.
• Check the label print: real labels use crisp, consistent fonts and colour. Blurry text, slightly-off fonts, wrong shades, or a label that sits crooked or has visible edges are red flags.
• Find the security features: PSA labels carry a UV-reactive layer (hidden logos that glow under a blacklight) and modern labels include a QR code that opens the cert page. BGS and SGC have their own holograms and label features. Missing, dull or wrongly-placed holograms are a warning.
• Inspect the seams and weld: graded cases are factory-sealed (PSA ultrasonically welds its holders). Look for glue, tooling marks, mismatched halves, gaps, or a seam that looks re-joined — all signs the slab was cracked and re-sealed around a different card.
• Feel the weight and thickness: compare against a slab you know is genuine if you have one. Fakes are often lighter, thinner or made of a slightly different-feeling plastic.

What are the seller red flags with graded cards?

Long before you handle a slab, the listing and the seller tell you a lot. With graded cards specifically, watch for these:

• A seller who won't share the cert number before you pay — there is no good reason to refuse this.
• Stock or blurry photos instead of clear, in-focus images of the actual slab, front and back, including the label.
• A price well under recent sold prices for that card in that grade — a genuine high grade rarely sells cheap.
• Implausible population numbers: a brand-new card listed as an ultra-low pop, or several "gem mint" copies of a scarce card from one new account.
• A new or low-feedback account listing multiple high-value graded cards at once, or pushing you to pay off-platform.

Does this work the same for BGS and SGC slabs?

The method is identical across the three graders Australians mostly use — only the specific features differ. PSA, Beckett (BGS) and SGC each have a free online cert lookup and each builds security features into its label and holder. So the routine is always the same: verify the number on the right grader's site, match the card to the reference photos, then inspect the label, holograms and seams of that brand's case.

What changes is the detail you're checking. Each grader's label layout, hologram and holder construction look different, so the best reference is a known-genuine slab from the same company — or the grader's own images of current labels. If you can't confidently tell a brand's real label from a fake, that uncertainty is itself a reason to slow down on an expensive card.

When should I just buy in person or through authentication?

The higher the value, the more the physical handover matters. For an expensive graded card, buying in person — at a card shop or a show — lets you inspect the slab under good light and a loupe before any money changes hands. A seller who won't let you handle the slab is telling you something.

Online, prefer channels that give you recourse. eBay Australia's Money Back Guarantee covers items that arrive not as described, and eBay runs an authentication programme on eligible higher-value cards (check the current eBay.com.au terms for what qualifies, as the thresholds and categories vary by market). And the surest way to remove slab-swap risk entirely is to trade with people you already know — see the safe trading guide for the bigger picture, and the fake raw-card guide for cards that aren't graded.
