At a Pokémon trade night, prevent slab-swap confusion by giving every graded card a unique inventory record and updating it when ownership changes. A "slab swap" means trading one professionally graded, sealed card for another, sometimes with cash or ungraded cards added. Certification numbers, grades, and small card variations can be difficult to track at a crowded table. A simple record, controlled table layout, and deliberate handoff process help prevent honest mistakes and provide evidence if a disagreement arises.

Build an inventory before trade night
Record enough information to distinguish each slab from every similar copy. A card's name and grade are not sufficient because two holders can contain the same card in the same grade. For each slab, capture: Place the inventory ID on a removable outer sleeve or team bag, not directly on the slab.
The label should remain readable without covering the grade or certification number. Treat asking values as temporary notes rather than permanent card attributes. Market references change, while the slab's certification number and physical details normally remain stable.

Give every slab a defined table status
Divide the table or carrying case into clear zones for "mine," "theirs," "pending," and "completed." A slab should occupy only one zone at a time, even if several people are discussing a larger trade. Handle one transaction at a time. When multiple negotiations overlap, a card can return to the wrong case or be counted in two proposed deals.
Use a small pending tray for cards under active consideration. Before anyone removes a card from that tray, state whether it is being returned, traded, or moved into another proposal. keep personal storage closed when it is not in use. If another collector wants to inspect a slab away from the table, agree on the handoff and keep the card within the transaction area.
Match the holder, label, and card
Compare the physical slab with its inventory entry before valuing it. Confirm the grading company, grade, certification number, card number, language, and visible variant rather than relying on the featured Pokémon alone. If the grading company offers certification lookup, compare the returned record with the slab's label. A matching database result supports the identification, but it does not by itself prove that a physical holder is genuine or unaltered.
Inspect the holder under good light for cracks, separation, label irregularities, or damage hidden by an outer sleeve. Do not declare a slab counterfeit based on one unusual feature; grading holders and labels may vary. Pause the deal when the holder, label, card, and lookup record do not agree. Photograph any meaningful holder damage before completing the trade. This prevents a later disagreement over whether a crack or deep scratch existed during the exchange.
Record the complete value exchange
Match price references to the exact card, grade, grading company, language, and variant whenever possible. A sale involving another grade or a different printing may offer context, but it is not a direct comparison. Write down every component before the cards change hands. For example: "Slab A plus $40 for Slab B and raw card C" is clearer than recording only the two main graded cards.
Any comparable sale is a reference point, not a guaranteed value. Differences in timing, venue, holder condition, buyer interest, and transaction terms can affect what two collectors accept. If cash is involved, count it openly and record which side paid it. Avoid leaving an unlabeled cash pile beside several pending trades.
Close and reconcile each trade
Before the final handoff, both collectors should read the deal back from the written record. Compare every certification number with the slab being transferred, then mark each inventory entry as incoming or outgoing. A compact trade log should include the date, counterpart's preferred identifier, outgoing items, incoming items, cash adjustment, and transaction status. Share contact details only with consent, and avoid photographing unrelated people or collections.
If a slab goes missing, stop moving cards and review the pending area, trade log, and photographs in sequence. Ask the organizer for help without accusing another attendee before the records establish what happened. Before leaving, compare every remaining slab against the inventory and resolve all pending entries. Do not pack the pending tray until every slab in it has a recorded owner and disposition.
