How to read a Pokémon card price chart
What a card price chart actually shows, why the median of recent sales beats the last sale, how to spot a thin market, and how grade and edition change the picture.
A price chart for a graded card looks simple: dots for sales, a line for the trend. Reading it well is what separates a buyer who gets a deal from one who buys the top. The rules below apply to any card price chart, including the ones on our card price pages.
Sales, not listings
Only recorded sales belong on a price chart. Asking prices are what sellers hope for; a card can be listed at $5,000 for a year without ever being worth it. If a site's chart moves on listings, ignore it.
The last sale is one data point
The newest sale is the most tempting number and the least reliable. It can be a damaged slab, an auction that ended at 3 a.m., a bidding war between two people, or a plain error. Use the median of the newest three to five sales instead: it tracks the market just as fast and ignores the outliers. That median is the headline number on our card pages.
How many sales back it up
A median of three sales in the last 30 days is a price. A median of one sale in the last 90 days is a guess. Charts should show how many sales they rest on; when the count is low, widen the window, look at the neighbouring grade, or accept that the price is uncertain and bid accordingly. Our pages show the sale count per grade and mark thin markets.
Grades are separate markets
Never mix grades on one line. A chart that blends PSA 9 and PSA 10 sales will show false crashes and rallies every time the mix changes. Read each grade on its own, then compare them. The gap between grades is itself useful: see PSA 10 vs PSA 9.
Editions and variants are different cards
1st Edition, Shadowless, Unlimited, reverse holo, Japanese and English printings all sell at different prices. A chart that pools them is a chart of a mix. Check that the card page you are reading is the exact printing you are buying.
Trend versus noise
Graded card prices move in waves tied to set releases, grading backlogs, the broader collectibles market and attention on social media. Week-to-week wiggles of 10% to 15% on a card are noise. A move that holds for two months across several grades is a trend. Compare a card to its set or to the overall Pokémon index on the same chart before concluding that it specifically is rising or falling.
What to take from a chart before buying
- The median of recent sales in your grade, and the count behind it.
- Whether the last 90 days are flat, rising or falling against the set.
- Where today's live listings sit against that median. The deal finder shows this for every live auction and Buy It Now it tracks.
See it live: every graded card auction and Buy It Now in the deal finder is priced against its recent sold comps.

Why does the same card show different prices on different sites?
Different sales windows, different handling of outliers, and sometimes listings mixed in with sales. Compare the method before the number: recent recorded sales, per grade, with the count shown.
Is the average or the median better for card prices?
The median. One sale at twice the going rate drags an average up for weeks; a median ignores it.
How often do graded card prices change?
Liquid cards reprice every few days as sales come in. Thin cards can sit at a stale price for months and then jump on a single sale, which is exactly why the sale count matters.
