If a seller denies a Pokémon slab mismatch, focus the dispute on what the listing promised and what arrived. A slab is a card sealed in a grading company's tamper-evident holder with a grade and certification number. Do not try to prove the seller's motive. Build a short record showing the listing, the delivered slab, the identifying differences, and the remedy you requested.

What Actually Proves a Mismatch?
The strongest evidence connects the purchased item to the delivered item through details that should match. Compare the card, grading company, grade, label variation, certification number, set name, card number, and listed condition. A different certification number is important, but it may not prove the entire case alone.
A seller might have disclosed that the listing used a stock photo or represented one of several equivalent slabs. Look for several consistent differences. For example, the listing may show a grade 9 slab with one certification number, while the package contains a grade 8 slab with another number and visible card damage.
Build a Compact Evidence Package
Reviewers need a record they can understand quickly. Preserve original files whenever possible because cropped images can remove useful timestamps, order details, or listing context.
Create a small, ordered evidence set: If you recorded the package opening, preserve the original video. Submit a short excerpt only if the dispute system accepts video and the footage clearly shows the sealed package and slab.
- The order confirmation showing the item and seller.
- Full screenshots of the title, description, photos, and disclosed terms.
- Clear photographs of the delivered slab's front, back, label, and certification number.
- The shipping label and packaging that connect the delivery to the order.
- A brief timeline covering purchase, delivery, seller contact, and response.
Keep the Claim Narrow
Describe the issue as "item not as described" or the closest available dispute category. Avoid calling the seller a scammer, alleging a counterfeit, or debating the seller's intent unless separate evidence supports those claims. Use specific language: "The listing pictured certification number 123 and a grade of 9.
I received certification number 456 and a grade of 8." That statement is easier to assess than "This slab is wrong and the seller knows it." Separate the mismatch from price arguments. Market value can change, while certification numbers, grades, and card identities remain concrete. Lead with the objective difference even if the delivered slab is worth less.
Responding to a Seller's Denial
Reply once with the comparison and requested resolution. Address any factual explanation the seller gives, but do not let the conversation expand into unrelated grading opinions, accusations, or collecting history. If the seller does not resolve the problem, use the marketplace's dispute process before its stated deadline.
Platform rules, evidence limits, return procedures, and payment-dispute options vary, so check the terms attached to that specific transaction. Do not return the slab outside the authorized process or without trackable shipping. Photograph the slab and packed return, retain the receipt, and save the tracking page showing its final delivery status.
