How we price Pokémon cards

Ungraded prices

An ungraded price is for a single, near-mint English copy of the card. It combines recent completed sales with current marketplace prices. Asking prices alone are not treated as a card’s value: a listing is what a seller hopes for, a sale is what a buyer paid.

Where a card was printed in more than one way (holo and reverse holo, for example), prices for the other printings are listed separately on the card page when we have them. If a card’s marketplace price sits more than three times above what it has actually sold for ungraded, and it has at least five ungraded sales in 90 days, we show the median of those sales instead and mark it limited. The Espeon ☆ (POP Series 5) page shows all of this in one place: the ungraded price, graded values, history and the sales behind them.

Graded prices

Graded prices come from sales of slabbed copies at that exact grader and grade. A PSA 10 and a PSA 9 are different markets, so they are priced separately, and PSA, CGC, BGS, SGC and TAG slabs are never mixed. We only show a grade when there is evidence for it; a missing grade means we don’t have enough sales, not that the card is worthless.

Rankings such as the most valuable cards are ordered by ungraded value only. Graded values are shown alongside, but a single gem-mint slab never moves a card up the list.

Recent sales

Card pages list recent sold listings. Before a sale is shown, we remove listings that don’t match the card: lots and bundles, multiple copies, non-English cards, slabs listed as ungraded, and titles whose card number doesn’t match. Some mismatches will still slip through, so the price itself is always built from many sales rather than any single one.

How confident is each price?

Each price carries one of three marks. They describe the evidence, not the card.

• Strong dataMany recent comparable sales that agree closely.
• Moderate dataSome recent sales, or sales that vary more.
• Limited dataFew recent sales. Treat this as a rough guide.

A price whose low and high estimates sit far apart is never marked strong, and a graded price backed by fewer than three sales is always marked limited.

Price changes and history

Older history is recorded as monthly averages and recent history as daily prices. On the chart, daily prices are shown as a 7-day average, so the line joins the monthly record smoothly and a single unusual day doesn’t swing it. Changes on the chart, such as “90 days”, compare today’s 7-day average with the line at that earlier point. Our source sometimes reports another printing’s price for a card for a few days; where the line jumps fivefold from one reading to the next, we don’t show a change across it.

Currencies

Prices are recorded in US dollars. Other currencies are converted using the European Central Bank reference rate from Sep 28, 2026. A converted price shows what the US market value is in your currency. It is not a local market price, which can differ because of shipping, fees and supply.

What these prices are not

Ultraball doesn’t buy or sell cards, and a price here is not an offer. Condition matters a lot: a played copy sells for less than the near-mint price shown. If a price looks wrong, check the recent sales on the card page. They are the evidence behind the number. To look a card up, browse by set or by Pokémon.
