Look up the same Pokemon card on three different sites and you can easily see three different prices. That is not a mistake, and none of the sources is necessarily lying to you. Each measures a slightly different thing, in a different market, at a different moment. This guide explains what eBay sold listings, Cardmarket, TCGplayer and dedicated price guides actually show, why they disagree, and how a UK collector should read them together.
The main sources at a glance
There is no single official price for a Pokemon card. Instead there are several sources, each built from different data. Knowing what each one is made of is the first step to reading it sensibly.
The four you will meet most often are eBay sold listings, Cardmarket, TCGplayer and standalone price guides or apps. They overlap, but they are not interchangeable.
- eBay sold/completed listings: real prices that real buyers actually paid, item by item. The rawest signal, but noisy and mixed with graded cards and bundles.
- Cardmarket: a large European marketplace with its own price statistics (trend, average, low). Strong for UK and EU buyers because it is priced in euros and ships within Europe.
- TCGplayer: the dominant US marketplace, with a widely quoted market price. Excellent depth, but US-centric and priced in dollars.
- Price guides and apps: aggregated estimates pulled from one or more of the above, often smoothed over time. Convenient, but only as fresh and as transparent as their underlying feed.
Why the same card shows different prices
The differences are not random. A handful of predictable factors push each source apart, and once you can name them you can mentally adjust for them.
Read a price alongside these factors rather than in isolation. A figure with no context, no date and no sample size behind it is close to meaningless.
- Currency and region: TCGplayer quotes US dollars for a US market; Cardmarket quotes euros for a European one. Converting to pounds still leaves genuine regional demand differences.
- Marketplace fees and postage: an eBay sale price includes what a buyer paid to a private seller; a marketplace 'from' price may exclude postage. Like-for-like is rarely like-for-like.
- Condition and grading: a raw near-mint card and a professionally graded copy of the same card are effectively different products. Sold listings often blend both unless you filter carefully.
- Recency: guides smooth prices over days or weeks, so they lag sudden moves. A single fresh eBay sale can be sharper but also a one-off.
- Sample size: three sales tell you far less than three hundred. Thin data on a rare card swings wildly; popular cards settle into a tighter range.
Reading eBay sold listings well
eBay sold listings are the closest thing to ground truth because they are actual completed transactions, not asking prices. That makes them valuable, but only if you filter them properly.
Search the exact card, set and number, then filter to Sold Items. Scan the results rather than fixating on the top figure. Look for a cluster of similar, recent sales and treat that band as your estimate. Discard obvious outliers: graded copies, lots and bundles, misdescribed cards, and international sales with heavy postage baked in.
A common trap is comparing an ungraded card you own against sold prices that are mostly PSA or CGC graded copies. Graded cards routinely sell for a large multiple of raw ones, so mixing them inflates your expectation.
Cardmarket, TCGplayer and price guides
Cardmarket is usually the most relevant marketplace for UK and European collectors. It aggregates many sellers and publishes its own statistics such as a trend price and an average, which helps smooth out individual odd listings. Because it is euro-denominated and Europe-based, its numbers tend to sit closer to what a UK buyer actually experiences than US figures do, though you will still convert currency and factor in postage.
TCGplayer is the deepest data source overall thanks to the size of the US market, and its market price is widely cited across the hobby. For a UK collector it is a useful reference for relative value and trend, but the absolute figure reflects US demand and dollars, so treat it as a signal rather than a price you will pay here.
Dedicated price guides and apps sit on top of these marketplaces. Their strength is convenience: one lookup instead of five tabs. Their weakness is that they are only as good as their inputs. A guide that hides where its number came from, or when it was last updated, asks you to trust it blindly. The better ones show source and freshness so you can judge for yourself.
A practical routine for UK collectors
You do not need to check every source every time. A quick, consistent routine gets you a defensible estimate in a couple of minutes.
The goal is a sensible range, not a single magic number. Anyone quoting a Pokemon card's value to the exact penny is overstating what the data can support.
- Start with recent eBay sold listings for the raw, ungraded card to anchor a realistic band.
- Cross-check Cardmarket for a European view and TCGplayer for depth and trend direction.
- Convert currencies to pounds and mentally add postage and fees before comparing.
- Weight recent sales over old ones, and larger samples over one-off results.
- If sources disagree wildly, trust the one with the most recent, most relevant, largest sample and note the uncertainty.
Where PokeChex fits
PokeChex is built around this reality rather than around a single magic figure. When you scan a card, it pulls raw value context from available catalogue and marketplace signals and shows the source and how fresh it is, so you can judge the estimate instead of taking it on faith. It is UK-first, so the framing suits how British collectors actually buy and sell.
It is deliberately honest about limits: PokeChex gives raw estimates with visible source and freshness, not live-guaranteed, graded or exact prices. It is not affiliated with The Pokemon Company, Nintendo, eBay, Cardmarket or TCGplayer, and it is not a substitute for checking recent sold listings yourself on a card that really matters to you. Think of it as a fast first read that points you at the right sources to confirm.
Frequently asked questions
Why is my card cheaper on Cardmarket than on TCGplayer?
Usually currency and region. TCGplayer reflects US dollar demand while Cardmarket reflects European euro demand, and the two markets genuinely differ. Convert to pounds and factor in postage before comparing, and remember a marketplace 'from' price is not the same as a completed sale.
Should I trust eBay sold prices or a price guide?
Both, for different reasons. eBay sold listings show what buyers actually paid, which is the strongest raw signal, but they are noisy and mix graded with raw cards. Price guides smooth that noise but lag sudden moves and depend on their sources. Cross-checking the two gives you a more reliable range than either alone.
Does PokeChex give exact or live prices?
No. PokeChex shows raw value estimates with the source and freshness visible so you can judge them, rather than claiming live-guaranteed, graded or exact figures. On a high-value card, always confirm against recent eBay sold listings yourself.
