Active listings: the active ungraded listings (eBay, tracked sets) the radar holds for this card — a count of what is offered, never of what sold; graded copies are not counted. Over 25 readings in 30 days the day-to-day moves had a standard deviation of 3.78%.

Price history

Cardmarket trend and low, one reading a day, on a real time axis: where the line breaks, the source was not re-read for more than three days, and nothing is drawn to fill the hole.

Printings

Each printing is a different product with its own price. Cardmarket in euros and TCGplayer in US dollars, side by side and never converted: two markets, not one price.

The headline figure above is the lowest-priced Cardmarket printing — the conservative reference the whole site keys on. A first edition or a shadowless copy is priced in its own row.

Observations of public market figures, not appraisals: Cardmarket’s European figures for ungraded copies via TCGdex, TCGplayer’s US figures via pokemontcg.io. Under the Holo is not affiliated with Cardmarket, TCGplayer, TCGdex, eBay or The Pokémon Company.
