A high-value trade is a logistics problem, not a trust exercise. Photograph everything, agree the terms in writing, and post with a service that is signed for and insured to the full value.
Key takeaways
- Agree in writing what each card is, its condition, who pays postage and what happens if a card is damaged or lost.
- Photograph both cards, both sides, and film the packing process without cuts.
- Send simultaneously with tracked, signed and fully insured postage, and exchange tracking numbers.
- Check the insurance limit of the service against the card's value — the cheap options do not cover much.
- For very large trades, use a mutually agreed third party or a platform that holds funds rather than a handshake.
Trades go wrong far more often through ambiguity than dishonesty. Two people remember a condition description differently, a parcel is left on a doorstep, or nobody agreed who covers a loss. Every one of those is solvable in advance.
Before anything moves
- Write out both sides of the trade: card name, set, number, printing, condition, and agreed value.
- Exchange clear photos, front and back, plus an angled surface shot of each card.
- Agree the postage service, who pays, and the insured value on each side.
- Agree the inspection window — for example, both parties confirm within 24 hours of delivery.
- Agree what happens on damage or loss, and stick to it if it happens.
Packing to a standard
- Penny sleeve, then a rigid holder or card saver, taped closed but never taped to the card.
- Sandwich between card or foam, into a rigid mailer, then a waterproof outer.
- Film continuously: card in hand, into the sleeve, into the holder, into the packaging, sealed, with the label visible.
- Do not write anything on the outside indicating trading cards. Discretion reduces theft.
Choosing a postal service
In the UK, the practical choice for valuable cards is a guaranteed, signed-for service with a compensation level at or above the card's value; Royal Mail publishes the compensation limits for each of its services and higher limits cost more. Check the current limit on the day you post, and never assume a standard tracked service covers a four-figure card.
When to use a middle party
- Either card is worth more than you could absorb losing.
- The other party has no relevant trading history you can verify.
- The trade crosses borders, where customs and recovery are much harder.
- In those cases, use a marketplace that holds payment, a reputable shop as intermediary, or simply sell and buy separately with protection on both transactions.
If a trade feels risky, selling to us and buying what you want removes the counterparty entirely — one accountable transaction each way.
Sell instead of trading →Common questions
- How should I post a valuable Pokémon card in the UK?
- Sleeve it, put it in a rigid holder, pack it rigid and waterproof, and send it with a signed-for, guaranteed service insured to at least the card's value. Check the service's current compensation limit before you post.
- Is trading cards with strangers online safe?
- It can be, with written terms, photographic evidence of both cards, simultaneous tracked and insured postage, and an agreed inspection window. Without those, you are relying entirely on goodwill.
- Should I film myself packing a card?
- Yes, for anything valuable. An unedited video from card in hand to sealed package with the label visible is the strongest evidence you can produce if a buyer claims a swap or a non-delivery.
- What is escrow in card trading?
- It means a trusted third party holds the money or the cards until both sides have delivered. Marketplaces that hold payment until delivery perform the same function, which is why keeping a deal on-platform is safer.
