Treat the counterfeit slab as a warning to pause and inspect the entire estate collection, not as proof that every graded card is fake. A slab is the sealed plastic holder and label used to identify and grade a card; verify each one independently before pricing, buying, or selling it. First determine whether the problem is the holder, the label, the enclosed Pokémon card, or some combination. Keep the suspect slab intact and document the collection before separating cards or contacting sellers.

Preserve the Collection's Evidence
Photograph every slab from the front, back, edges, and corners. Record the grading company, certification number, stated card, grade, purchase paperwork, and storage location in an inventory. Keep cards grouped as they were found.
Shared boxes, receipts, submission forms, auction invoices, and correspondence may reveal which slabs came from the same source. One counterfeit could be an isolated purchase, while several related cards may indicate a larger problem. Do not crack, clean, relabel, or discard the suspect holder. Altering it can destroy evidence, damage a genuine card inside, and make a return or authentication review harder.
Identify What May Be Counterfeit
A "counterfeit slab" can describe several different problems. The distinction matters because it determines how much suspicion should extend to nearby cards. Look up the certification number through the grading company's official verification system when one is available.
Confirm that the listed set, card number, language, variant, grade, and images match the slab in hand. A valid database result does not prove the physical slab is genuine. Counterfeiters can copy real certification numbers, so treat the lookup as one check rather than a final answer.
- A fake card sealed inside a fake holder
- A genuine card placed in an unauthorized or counterfeit holder
- A real holder that was opened, altered, or fitted with a replacement label
- A copied certification number placed on a different card or holder
Sort the Remaining Slabs by Risk
Evaluate related groups before examining random cards. Slabs bought from the same seller, found with the same paperwork, or displaying the same unusual construction deserve priority. A practical sorting system is: Certification numbers near one another may suggest a shared submission, but number sequence alone proves little.
Grading companies also change labels, shells, and security features, so compare each slab with genuine examples from the correct period rather than only current holders. Lower risk does not mean authenticated. It means those cards can wait while you resolve the groups most likely to affect the collection's value.
- High risk: matching source, obvious label or holder problems, incorrect card details, or a copied certification number
- Medium risk: missing provenance, unfamiliar holder style, inconsistent printing, or cards valuable enough to attract counterfeiting
- Lower risk: documented submissions, consistent records, and holders matching known genuine examples from the same grading era
Inspect Both Holder and Card
Examine the holder under bright, indirect light. Check the seams, welds, label alignment, print sharpness, internal supports, logos, and security elements appropriate to that holder generation. Cloudy plastic, rough edges, or an imperfect seam may justify scrutiny, but manufacturing wear and later damage can resemble tampering.
Then inspect the enclosed card with magnification without opening the slab. Compare it with a trusted example of the exact set, language, printing, and variant. Check for: No single visual sign settles authenticity. Genuine Pokémon cards can have print defects, off-center cuts, color variation, surface wear, and unusual factory characteristics.
- Incorrect typefaces, symbols, wording, or card numbering
- Colors or borders that differ substantially from genuine examples
- A holographic pattern that does not belong to that release
- Blurry fine text or an implausible printing pattern
- Card dimensions or alignment that conflict with the holder and label
Decide What Needs Professional Review
Start with slabs that combine high value and high risk. Authentication fees, shipping, and insurance may not make sense for every inexpensive card, but one expert review can help identify repeated defects across a related group. Contact the named grading company through its official channel and provide clear photographs, the certification number, and the reason for concern.
For a second opinion, choose an experienced Pokémon authenticator or dealer who has no financial stake in buying the collection. Do not list a suspected counterfeit as genuine or rely on a disclaimer to excuse an uncertain description. Preserve receipts and communications if a return, estate claim, marketplace report, or payment dispute may follow. Until each questionable item is resolved, place it in a protective sleeve labeled "hold—not for sale," with its inventory number and photographs attached to the record.
