It arrived. It was a Base Set Blastoise, and it was in a PSA slab. The grade was PSA 6.
When I went back and actually read the description — which I should have done first — there it was, buried near the bottom: “Pictured card shown as example. Actual grade PSA 6.” The title was engineered to mislead, the description was technically honest, and I’d skimmed straight past it.
The platform sided with the seller on the wording. I was out £450 on a card worth perhaps £80.
It was an expensive way to learn a cheap lesson: on the secondary market, the title is marketing and the description is the contract.
This chapter is about not learning that the way I did.
It assumes you’ve already got a feel for value and condition from the first two chapters — buying well depends entirely on being able to judge both.
It won’t teach you to “win” the market or extract the maximum possible pound from every sale.
The aim is steadier than that: buy without getting scammed, sell honestly enough that buyers trust you, and avoid the handful of mistakes that cost people real money.
The “Sold items” filter is the single most useful tool in collecting. It shows what cards actually change hands for, not what optimists are asking.
The trade-offs are scam exposure — misleading titles, swapped slabs, bait-and-switch — and fees that meaningfully erode a sale.
Read the entire listing, check the seller’s feedback volume and recent history, and never move a transaction off-platform. The moment you do, your buyer protection evaporates.
Be realistic, though: it’s US-centred, so for a UK buyer the shipping and import costs often undo the benefit.
Treat it as a reference for modern prices and an option for staples you can’t source here, rather than a default.
They also carry the least protection, so the discipline matters more:
A good relationship with a shop pays off over time in better deals and first refusal on stock. You’ll usually pay a margin over online prices for the convenience and the ability to check condition in person — which is often worth it.
Know the market value before you walk in, and inspect thoroughly, because there’s rarely a return once you’ve left.
Treat any of these as a reason to slow down and verify.
Check sold listings. Anything 40%+ under market deserves real suspicion.
Request photos of that specific card, timestamped, with their username visible.
A seller’s opinion of what a card might grade is worth nothing. If it isn’t explicitly graded in the description, assume it’s ungraded.
For purchases over a couple of hundred pounds, favour established sellers.
It can signal a seller who knows about a problem and doesn’t want it coming back. For high-value buys, prefer returns-accepted listings or platforms with buyer protection.
Off-platform means zero protection. Decline, and report it.
None of the advice below is about squeezing buyers. It’s about removing doubt.
For example:
Charizard Base Set Unlimited Holo PSA 9 — WOTC 1999
Use the space you’re given, but don’t imply a grade the card doesn’t have.
For graded cards, add the full slab front and back and a close-up of the label and cert number.
Good photos pre-empt most disputes.
For example:
Near Mint, with minor edge whitening on the top-right corner, visible in photos. Shipped in penny sleeve, top loader and bubble mailer, tracked. Returns accepted within 30 days if not as described.
Accepting returns genuinely increases buyer confidence and tends to lift the price people will pay.
For bulk and commons, price at or just below market to move it.
For mid-tier cards, roughly £20–£200, price at market with offers enabled.
For higher-value cards, you can either set an auction with a sensible reserve or list at a fair fixed price and wait for the right buyer.
Never start a valuable card at 99p hoping a bidding war materialises. If it doesn’t, you’re obliged to sell at whatever it reached.
In UK terms, Royal Mail Special Delivery is usually the sensible choice for higher-value cards.
The rule that has no exceptions: never send a high-value card uninsured.
Post does go missing, and if it does, an uninsured loss is yours to absorb. A few pounds of cover against a several-hundred-pound risk is not a decision worth agonising over.
Postage tiers and prices change, so check the current service level and insurance cover before sending anything valuable.
If the complaint is fair, accept the return.
If a buyer claims non-receipt, your tracking is your protection. Platforms generally side with a seller when tracking confirms delivery, which is why tracked — and, for valuable items, signed — postage is non-negotiable.
Requests for a partial refund are a judgement call. Offer a full return, or a partial reduction if you genuinely understated something.
For damage in transit, photograph it immediately before unpacking further, and the seller should either refund or claim on the insurance.
For an item that never arrives, allow tracking a reasonable window to update, typically a week or two past expected delivery, before escalating.
If tracking never shows delivery, a dispute will normally go your way.
Whether you use a tool or do it manually, it’s a reasonable way to buy.
Sellers of stale inventory are often glad to move it.
Grading is subjective, your resubmission can come back the same or lower, and you’ve destroyed the original slab to find out.
Only consider it if the PSA 9 price is low enough that you break even on a failure and the 10 premium is large — and even then, recognise it for the speculation it is.
It’s a small business, not a shortcut. It doesn’t belong in a beginner’s plan.
As a buyer, verify everything and lean on the protections that exist.
As a seller, be transparent enough that there’s nothing to dispute.
Five minutes reading a listing properly would have saved me £450. Don’t learn it the way I did.
The next chapter turns to the bigger picture these transactions sit inside — how the Pokémon TCG market moves in cycles, why prices spike and correct, and how to avoid buying at the top of the hype.
