Treat a Pokémon slab offered by private message as unverified until the seller proves possession and accepts safe transaction terms. A slab is a graded card sealed in a numbered holder, but the holder and certification number alone do not prove the offer is genuine. Private sales can be legitimate, especially within collecting communities. The risk rises when the seller initiates contact, creates urgency, or asks you to abandon normal buyer protections.

Confirm the seller has the exact slab
Ask for a new photograph showing the slab beside a handwritten note with the seller's username, the date, and a phrase you choose. Request clear images of the front, back, label, holder edges, and certification number. A timestamped image is stronger than a listing photo, but it is not conclusive. A scammer may alter images or briefly possess a card they do not intend to ship.
A live video showing the requested details can provide another check. Search the seller's images to see whether they appear in older listings or posts from another account. Also review the account's history, collecting activity, and completed transactions. Account age and references help establish context, but neither guarantees honesty.
Check the card, label, and holder
Enter the certification number on the grading company's official website, reached through an address you type or find independently. Do not trust a link or QR-code destination supplied by the seller.
Confirm that the database entry matches every visible detail: A matching record only shows that the certification number exists. Counterfeit holders can copy numbers from genuine slabs. Look for inconsistent fonts, crooked labels, damaged seams, unusual plastic, or card details that differ from the official record.

Decide whether the price makes sense
Compare the offer with completed sales for the same card, printing, grader, and grade. Asking prices show what sellers want; completed sales better indicate what buyers have recently accepted. Check whether the slab has features that change its value, such as a first-edition mark, regional printing, error, autograph, special label, or grade qualifier.
When few comparable sales exist, treat any valuation as a range rather than a precise market price. Ask for the complete delivered cost, including shipping, insurance, taxes, and fees. A price far below comparable sales does not prove fraud, but it warrants stronger verification and no concessions on payment protection.
Keep payment and shipping protected
Use a marketplace checkout or payment method that explicitly covers collectible purchases and items that arrive counterfeit, damaged, or materially different from the description. Read the applicable terms because "goods and services" labels do not guarantee coverage in every situation. The invoice should identify the exact card, grading company, grade, certification number, price, and promised condition. Keep the private messages, invoice, photographs, payment record, and shipping details.
Avoid payment methods designed for gifts or irreversible transfers, including friends-and-family payments, cryptocurrency, gift cards, and direct transfers to strangers. Tracking, insurance, and signature confirmation reduce delivery disputes, but they do not authenticate the slab. For an expensive local purchase, meet at a recognized card shop or another safe public location where you can inspect the slab before paying. Do not let the seller switch the payment recipient, shipping address, or terms at the last moment.
Know when to stop replying
End the discussion if the seller refuses a requested possession photo, gives inconsistent card details, pressures you to pay immediately, or insists that buyer protection is unnecessary. Treat requests for login codes, remote access, identity documents, or unrelated deposits as separate danger signs.
A concise response keeps the burden of proof on the seller: "Please send a current timestamped photo and an invoice listing the certification number. I will only pay through a protected purchase method." If the seller will not meet those conditions, do not negotiate around them. Save the messages, report the account through the relevant platform, and leave the payment unsent.
