What your Pokémon cards are worth
Comps, condition and grading — how card values are actually set, and how to read a price without getting fooled by an optimistic listing.
Value is a chain of decisions
There's no single price for a card — there's a chain of decisions that narrows a character down to a specific piece of cardboard, and then to what buyers have actually paid for that cardboard lately. Each link below moves the number, sometimes by multiples.
Sold comps beat asking prices
An active listing is what a seller hopes to get. A completed sale is what a buyer actually paid. Serious valuations weight recent sold prices most heavily, trim the outliers at both ends, and only fall back to listings when a card hasn't sold recently.
The exact printing matters
The same character can span dozens of printings: set, collector number, rarity, holo or reverse holo, first edition, promo stamps. Two cards that look near-identical can be worth wildly different amounts, so matching the precise printing is the first job — not an afterthought.
Language changes the market
Japanese printings trade on their own market with its own prices — sometimes higher, sometimes lower than English. A Japanese Umbreon is priced against Japanese sales, even if you track it under its English name in your records.
Condition multiplies (or divides)
Near mint, lightly played, moderately played, heavily played, damaged — each step down the scale takes a real bite out of value. Honest condition assessment is where most pricing mistakes happen, in both directions.
Grading changes the comp set entirely
A graded card is a different product. A PSA 10 doesn't follow raw near-mint prices; it follows PSA 10 sales, and a CGC 9.5 sits somewhere else again. The grader and the numeric grade both belong in the price lookup.
When the market is thin
Vintage, foreign-language and niche promo cards often have few recent sales. The honest move is to widen the time window, fall back to current listings, and label the result as an estimate — a number built from two sales is not the same kind of number as one built from fifty. Any tool (or person) that presents a thin-market price with the same confidence as a liquid one is asking you to take risk you can't see.
From value to decision
Knowing a card's worth is only half the job. If you're buying, trading or selling, the market value becomes three working numbers — a cash offer, a trade value and a sale price — each a deliberate percentage of market. That's covered in our trade vs cash pricing guide.
Cardinal does the whole chain in one scan: it identifies the exact printing and language, reads sold comps across multiple marketplaces, applies condition — and for slabs, uses the grader and grade to pull graded prices instead of raw ones — then turns the result into your buy, trade and sale numbers. Thin markets are flagged so you know when you're looking at an estimate.
