Check the Real Market Price of Any Trading Card

There are two ways to check a card's value on Citadel. The fastest is to scan it: point your phone camera at the card, and the AI identifies the exact printing — the set, rarity, foil or non-foil treatment, and collector number — then attaches the current market price automatically. The second way is to search the public catalog by card name, browse the matching printings, and open the one you own to see its price. Both methods return the price for that exact variant, not a rough average across every version of the card. That distinction matters: a foil printing from a small set can be worth many times more than a non-foil version of the same card from a mass-market reprint, and a graded slab is priced differently again. Because Citadel prices at the printing level rather than the card-name level, you always see the value of the specific copy you're holding, whether you scan it or search for it in the catalog.

Every price on Citadel is based on live European market data, drawn from real sellers listing and selling cards to buyers across the continent. Citadel stores each printing's price in euros and refreshes it daily, so the value you see reflects current market activity rather than a stale snapshot from months ago. Because many other price trackers pull only from US marketplaces, their numbers can feel disconnected from what a card actually sells for in Europe — a set that is common in the US market can be scarce, or vice versa, in the European one. Citadel converts the euro price automatically to US dollars and British pounds, so collectors outside the eurozone still get a number in their own currency without doing the math themselves. The result is a price that reflects European market reality first, with USD and GBP shown alongside it as a convenient second reference rather than the sole source of truth.

The same card name can have very different values depending on which specific version you own. The printing or set matters first: a first edition or a low-print-run set is typically worth more than a later reprint of the identical card. Foil and non-foil treatments of the same printing are priced separately, and a foil is usually worth more because fewer were produced. Condition changes value too — a heavily played card sells for less than a near-mint copy of the same printing. Grading adds another layer: a card professionally graded in a slab is priced differently from the same card ungraded, and the assigned grade affects the value further. This is why comparing two cards by name alone can be misleading. Citadel's scanner reads all of this from a photo — the set, the foil treatment, and the grade if the card is slabbed — so the price it shows matches the exact copy you're holding rather than a generic average for the card name.

Yes, in two ways. Price alerts let you follow individual cards and get notified when they cross a target price — the free plan includes up to five active alerts, Lite raises that to twenty, and Premium removes the limit entirely. For tracking your whole collection's value over time, Citadel's Portfolio Analytics shows your total portfolio value, performance charts, top movers and return on investment across everything you own. Portfolio Analytics is included on the Lite and Premium plans; it is not part of the free tier. On Lite or Premium, your dashboard updates automatically as card prices change, so you can see whether your collection is gaining or losing value without checking every card individually. Between the two features, you can watch specific cards you're waiting to buy or sell with alerts on any plan, and get a full view of your collection's overall value if you upgrade to Lite or Premium.

Citadel covers seven trading card games today, and all seven are fully live rather than in development. Magic: The Gathering and Pokémon have the deepest catalog coverage, and Pokémon includes Japanese-language printings alongside English ones, which many price trackers leave out entirely. Yu-Gi-Oh!, Disney Lorcana and the One Piece Card Game are fully supported, and two newer games, Riftbound and Star Wars: Unlimited, are priced from their earliest sets onward. For every game, Citadel prices at the exact printing level — set, rarity, foil treatment and, where relevant, language — so a reprinted card is valued correctly instead of being averaged across every edition that shares its name. The table below lists each supported game, so you know exactly which collections you can check a value for today before you start scanning or searching.
