How to spot a fake slab

A slab's holder and label carry the grader's verdict and a certification number, and that is exactly what forgers copy. PSA's cert page says criminals, though uncommonly, counterfeit PSA grading inserts using real cert numbers taken from public sources; Beckett's director of grading said in 2021 that “there are fake BGS slabs out there right now.” This guide gathers what PSA, CGC and Beckett publish about their holders and labels, plus red flags from the hobby press, all read on October 14, 2026.

Three ways a slab can lie

Counterfeit cards are a separate problem that can end up inside a fake slab. Per Sports Collectors Digest's summary of PSA's 2025 fraud report, 821 of 3,285 1986 Fleer Michael Jordans submitted to PSA were counterfeit, and trading card games made up 56.3% of the counterfeits it caught.

Step 1: Check the cert the right way

1. Enter the label's cert number on the grader's own lookup (psacard.com/cert, CGC's Verify Certification page, gosgc.com/cert-code-lookup, Beckett's site), typing the address yourself rather than following a seller's link.
2. Or scan the label's QR code: PSA's LightHouse label, CGC's label and Beckett's 2026 label all carry one that opens the grader's verification record. Check that it lands on the grader's own website.
3. Compare every field (year, set, card number, name, variety, grade) with the label in front of you.
4. Compare images. PSA posts SecureScan images of higher-value items graded at Express level or above; CGC images every card after encapsulation. Centering, print marks and corner wear should match.
5. Remember the limit: PSA states that verifying a number “does not eliminate risk.” A forged label with a copied number passes a text-only lookup.

The lookup itself is covered in more detail in how to verify a slab's cert number.

Step 2: Know the published security features

Graders publish some anti-counterfeiting features (PSA also mentions covert ones it does not list). Compare a suspect slab with the grader's description and, ideally, a known genuine holder of the same era.

1. Label and cert number: look the number up on the grader's own site or scan the label's QR code, then compare every field and image (PSA, CGC, Beckett).
2. Security print: holograms or holographic foil, microprinting and UV-reactive ink; what is used and where varies by grader and label generation.
3. Welded seam: genuine holders are sonically or ultrasonically welded and feel rigid (PSA, CGC).
4. Card window: the card's centering, corners and print marks should match the grader's images and the grade claimed.
5. Light test: on an authentic PSA label you can make out text from the other side; a fake front stuck over a real label blocks the light (PSA).
6. Seam check: cloudy "frosting" or cracks along the seam, flex under light pressure or glue suggest a broken weld (PSA).

Step 3: Inspect the holder

• Frosting along the seam. PSA's buyer's guide says cloudy edges along the seam, sometimes with visible cracks, can mean the weld has been broken.
• Flex. A genuine weld feels rigid. A broken one feels more flexible, and light fingernail pressure may make it crack or pop open.
• Glue. Glue does not restore a sonic weld, so a glued holder may still flex or open.
• Thickness and markings. The fake BGS holders Beckett examined in 2021 were thinner than genuine ones, the patent number stamped on the bottom stood out more, and the inner sleeve was slightly different.
• Tamper evidence. PSA describes its holder as one that leaves evidence when someone tries to violate it. For PSA/DNA autograph encapsulation, its FAQ says certification becomes “null and void” once the item is removed or the holder shows tampering.

Step 4: Inspect the label

• The light test. PSA suggests holding the label up to a light at close range: on an authentic label you should be able to make out the text on the other side, though not necessarily word for word.
• Added layers. A fake front stuck onto a real label blocks the light, and parts of the genuine label may show beneath it. The fake BGS labels found in 2021 were two stickers stuck together, which was visible only once the case was taken apart.
• Security print. Look for the hologram or foil, microprinting and UV-reactive elements the grader describes for that label generation.
• Grade versus card. If the card looks weaker than the number claims, check it against the published standards in the PSA grading scale and the centering calculator. The 2021 BGS fakes were detected partly because 8.5 and 9 cards sat in 9.5 holders.

Step 5: Weigh the deal

PSA's buyer's guide puts the seller first: buy from a reputable dealer or auction house, ask for references, be wary of unsolicited too-good-to-be-true offers, and take a day or two if in doubt. You can ask PSA to review an item and make the deal contingent on it; a seller's hesitation may be an answer in itself. PSA's cert page does not recommend Craigslist, Mercari or OfferUp.

Supply is a clue too: in a 2007 case reported by Sports Collectors Digest, an authentication trainer flagged sellers with many copies of scarce cards and repeated identical auctions. PSA's 2025 report lists Charizard, Michael Jordan and Mickey Mantle among the most counterfeited subjects.

Quick checklist

• Cert looked up on the grader's own site (typed in or via the label's QR code).
• Every field on the record matches the label.
• The grader's images match the card in the holder.
• Label shows the security print described for its generation.
• Label passes the light test with no added layer.
• Seam is clear, with no frosting, cracks, flex or glue.
• Card's condition is consistent with the grade.
• Seller is known, with references, and agrees to a grader review if asked.

If a slab looks wrong

1. Hold off on paying until it is resolved, and keep the listing, photos and cert number.
2. CGC: its cert lookup pages ask you to contact CGC by email if the record does not match the card or if you believe you have a counterfeit or tampered CGC holder.
3. PSA: its FAQ points authentication questions to a Research Request in the Customer Request Center, with front and back images.
4. A genuine PSA slab with a wrong label can go through a Label Correction Request; PSA corrects mislabels free, but you pay return shipping if no error is found.
