Shortly after 30th Celebration launched worldwide on 16 September 2026, striking misprints began to surface. The best known is "Blood Mew": a Mew ex card with a red stripe running across its holofoil. The cause is very likely a splice between two foil rolls whose coloured tape was not caught by quality control, Dexerto explains.
Which errors exist
Misprint specialist Ruben Misprints sorts the reported cases into several groups: foil splices like "Blood Mew", extra magenta ink, holofoil on the card back, shifted or doubled images, water marks from printing, and miscuts.
What they cost
On Japanese platforms, misprints trade well above regular copies. Mew ex with a ghosted image went for roughly ¥20,000 to ¥150,000 according to Dexerto, against about ¥14,000 for a normal copy; Mewtwo ex misprints sold for ¥17,000 to ¥58,000 against about ¥10,000. Some misprint listings asked up to ¥3 million, though none sold at that price. Convincing fakes appeared just as quickly.
Pokémon has not commented on the errors. Japan does, however, have a formal exchange process for faulty cards: it requires the receipt and a purchase within the last two weeks, tradecard.jp reports.
