A livestream seller's claim is not proof; buyers can check the grading record, label details, holder construction, card characteristics, and sales trail. No single check proves authenticity, so the evidence must agree. A "slab" is a card sealed in a hard-plastic holder by a grading company. The crucial question is whether the holder, the enclosed card, and the assigned certification belong together.

Separate the three authenticity questions
An authentic-looking slab can raise three different questions: Is the card genuine? Is the holder genuine? Does the certification number belong to that exact card and grade? A seller may answer only one while implying all three. For example, a valid certification number proves that a grading record exists. It does not automatically prove that the slab on camera is the item described in that record.
Someone could copy a number or label details from a genuine slab. The grade is a separate issue. A genuine card in a genuine holder may still have been altered after its original sale, placed in a counterfeit holder, or paired with a copied label.
Check the certification record
Enter the certification number directly into the grading company's official lookup tool, if one is available. Avoid relying only on a link or screenshot supplied by the seller. Compare every displayed field with the livestreamed slab: Small inconsistencies matter. A record for a first-edition card does not support an unlimited card, even when the artwork is identical.
Likewise, a holographic version cannot validate a non-holographic card. A missing record is a serious warning, but it is not always final proof of fraud. Databases can contain errors, older records may be incomplete, and certification numbers can be entered incorrectly. Ask the grading company to confirm any unresolved discrepancy before paying.

Compare the slab with known genuine examples
Study the holder's shape, seams, label placement, text alignment, and visible security elements. Compare it with confirmed examples from the same grading company and label generation, because holder designs can change. Look for uneven plastic edges, a cloudy or disturbed seam, loose internal pieces, crooked printing, inconsistent fonts, or spelling errors. These are warning signs, not automatic verdicts.
Damage, manufacturing variation, and poor video quality can also make genuine holders look suspicious. Do not treat one familiar feature as decisive. Counterfeiters may copy logos, holograms, barcodes, and certification numbers. The complete holder should match the company's design for that certification period.
Inspect the card, not just the label
Ask the seller to show the card under bright, moving light and from several angles. A fixed front-facing view can hide surface damage, altered edges, incorrect foil, or a card that differs from listing photographs. Useful close-ups include the front, back, all four corners, edges, foil pattern, printed text, and the gap between the card and holder.
Compare the artwork, symbols, typography, colors, and card dimensions with a trusted genuine example of the same printing. Video has limits. Compression can distort colors and patterns, while glare can conceal scratches or trimming. Some authentication checks require magnification, measured dimensions, or examination outside the holder, which a buyer cannot perform during a livestream.
Preserve evidence before buying
Ask the seller to show the certification number and the entire slab in one continuous shot. If possible, have the seller display a handwritten note containing the date or your username beside it. This helps connect the offered item to the slab being shown. Save the listing description, seller claims, price, photographs, stream recording or screenshots, messages, payment record, and stated return policy.
Record any promise that the slab is genuine, unaltered, or eligible for verification. Use a payment method and marketplace process that provide a documented dispute route. Do not move the transaction off-platform merely for a discount if doing so removes buyer protection. After delivery, compare the received slab with the saved images before removing stickers or packaging. If the certification details, holder marks, or card features differ, photograph the unopened parcel, shipping label, packaging, and slab before contacting the marketplace, payment provider, grader, or seller.
