Step 1:
Identify the Exact Card, Not Just the Pokémon
To check a Pokémon card’s value, first confirm exactly which card you have (set, card number, variant and language), then judge its condition honestly, then compare recent sold prices for that exact version and condition, not asking prices. Finally, look at its price history so you know whether today’s number is typical, unusual or still settling.
A single number on a screen feels like an answer. Usually it’s the start of one. Two cards with the same name can be very different collectibles, and one price can hide a lot of what’s actually going on in the market. Here’s how to think through it, one step at a time.
Step 1: Identify the Exact Card, Not Just the Pokémon
The name “Charizard” alone doesn’t identify a specific printing. Before any price means anything, pin down:
Set. Check the set symbol and set name. Reprints and special sets can reuse classic artwork, so the same picture can show up in very different releases.
Card number. The collector number (for example, the “4/102” style printed on the card) separates cards in the same set and helps you avoid matching to the wrong listing.
Variant or printing. First edition vs. unlimited, holo vs. reverse holo, promo stamps and alternate arts can each be priced on their own.
Language. Match the language too. An English printing and a Japanese printing are not interchangeable price comparisons.
If any of these details is wrong, every price you look at afterward is for a different card.
Step 2:
Be Honest About Condition
Step 2: Be Honest About Condition
Condition is the next filter: small differences in wear can make two otherwise matching cards poor comparisons.
Ungraded (raw) cards are usually described with marketplace terms. TCGplayer’s Card Conditioning Overview uses Near Mint, Lightly Played, Moderately Played, Heavily Played and Damaged, based on the number and severity of imperfections like edge wear, scratches, creases and whitening. A “Near Mint” card can still have a few slight flaws, so check corners, edges, surface and centering under good light before deciding where yours fits.
Graded cards have been evaluated and sealed in a case by a grading company. PSA’s grading standards explain, for example, that a PSA 10 Gem Mint card needs sharp corners, original gloss and centering within set tolerances, and that grading still involves some judgment about eye appeal. A graded card and a raw copy of the same card are effectively different products with different prices, and so is the same card at different grades.
Two practical takeaways:
Compare raw to raw and graded to graded, with the same grading company and grade.
Don’t assume your raw card will match a high-grade price. “Ungraded” doesn’t mean “Near Mint.”
Step 3: Use Sold Prices, Not Asking Prices
An asking price is what a seller hopes to get. A reported sold price is evidence of a completed transaction, though accepted offers and listing details can affect what is publicly visible. Those can be far apart, especially on cards with few active listings.
Completed sales give price guides a reference point. TCGplayer says its Market Price is based on recent sales rather than current listings, and it filters out outliers.
When you look at sold listings yourself:
Match the exact card and condition from Steps 1 and 2.
Look at several sales, not just the most recent one. A single sale can be unusually high or low.
Read the listing. Bundles, damaged copies, mislabeled variants and best-offer sales can skew what you see.
Notice the date. Older sales may not reflect current conditions; check when each transaction occurred.
Step 4:
Read the Price History, Not Just Today’s Number
Step 4: Read the Price History, Not Just Today’s Number
Once you have a reasonable current value, zoom out. Price history helps you answer questions a single number can’t:
Is this price normal? Has the card sat in a steady range, or is today well above or below where it usually trades?
How stable is it? Some cards drift slowly; others swing hard around new set releases, reprints or bursts of attention.
How much data is there? Check the number and recency of comparable sales where available. A chart’s shape alone doesn’t show how much evidence supports it.
History adds context, but it doesn’t prove why a price moved, and it doesn’t tell you where it’s going next. A spike that lines up with a reprint announcement, for example, is a clue worth noticing, not a confirmed cause. Treat history as a way to understand what you’re looking at, not as a forecast.
Step 5:
Know the Limits of Any Price
Step 5: Know the Limits of Any Price
A guide or app estimates value; a sold listing records one transaction. Neither guarantees what another copy will fetch:
Thin markets. Rare or niche cards may have very few sales, so one transaction can move the “value” a lot.
Condition guesswork. Raw-card prices depend on how honestly sellers described condition.
Different sources, different numbers. Guides use different data and methods, so they won’t always agree. That’s normal.
Fees and shipping. The price a card sold for isn’t the same as what a seller kept after costs.
Knowing these limits is part of knowing your card.
Where Rune Fits
We built Rune around a simple idea: a price tells you how much. Rune helps you understand why. By “why,” we mean the context around a price: its history, movement and stability. We don’t claim to prove what caused a move.
According to its App Store listing, Rune for iPhone lets you scan and identify cards with your camera, search Pokémon TCG cards and sets, track your collection including printing and condition, and see current market values alongside historical movement and ranges. It’s a way to work through the steps above in one place, while still checking the details yourself.
Collecting tells you what you own. Understanding it takes a little more. Know Your Cards.
Built for collectors who want to know more.
Recognize. Understand. Navigate. Evaluate.
