Porygon-Z

The cheapest copy at £7.50 is flagged as MP condition, so a clean example will command more than that. UK sellers are asking well above Cardmarket—the 14 listings here price the card at roughly double the €3.52 trend—and most stock (54% of known grades) is played; a Near Mint copy is genuinely hard to find. Asks range from £7.50 to £11.90, leaving the lowest roughly 37% under the median, which tells you there's real daylight between the bargain end and what a decent copy will fetch.
