There is no industrywide two-person verification rule for high-value Pokémon slab trades. Instead, collectors can use it as a voluntary protocol: both parties independently inspect each slab—a graded card sealed in a plastic holder—and match it to its certification record before release. This process can catch mismatched labels, holder damage, and suspicious certification details. It cannot guarantee authenticity because, as PSA warns in its certification guidance, counterfeit inserts can display genuine public certification numbers.

Grading checks are not trade verification
PSA uses a second grader and final quality-control checks while grading cards. PSA's description of that workflow does not establish a two-person rule for private trades.
In a collector-to-collector transaction, "two-person verification" means each party performs the checks separately. One person should not simply read the certification result aloud while the other accepts that conclusion.
A practical two-person checklist
Keep both slabs visible and under their owners' control until the checks are complete. Each person should inspect the card being received, then repeat the process for the other slab.
Do not release either card while a discrepancy remains unexplained. A rushed handoff defeats the main benefit of having two separate checks.
- Read the certification number directly from the label.
- Enter the number independently, or scan the holder's QR code where available.
- Compare the database description and grade with the card and label.
- Compare database holder images when the grading service provides them.
- Inspect the holder's front, back, corners, and welded edges.
What should you inspect beyond the number?
For a CGC slab, the verification tool can display the card description, grade, and images CGC took of the holder. CGC explains that participants can search by certification number or scan the QR code, making a direct image comparison possible. The physical holder still matters.
PSA describes its holder as tamper-evident, not tamper-proof. Warning signs can include clouding around a broken weld, cracks, unusual flexibility, or edges that pop open. Treat a matching database entry as a cross-check, not proof. A real certification number attached to the wrong card, label, or holder can still produce a valid-looking lookup result.
When marketplace protection adds another check
For purchases rather than direct card-for-card swaps, eligible eBay listings priced or sold at $200 or more automatically enter Authenticity Guarantee. The program covers individual cards graded by PSA, CGC/CCG, SGC, or Beckett, but excludes local pickup and delivery to P.O. boxes, according to eBay's eligibility rules. Professional authenticators inspect the card or sealed graded holder before buyer delivery.
They do not grade or re-grade the card, and eBay excludes authentication of in-person autographs, aftermarket patches, and relics. The $200 figure is an eBay program threshold, not a universal definition of a high-value trade. When money is involved, the FTC advises using a credit card or protected payment system, keeping written messages and transaction records, and staying inside the marketplace's payment process. Paying outside the platform can forfeit its protection.
