How much is a Tentacool card worth?
It depends which one. We know the price of 13 Tentacool cards: here they are, dearest first. Each number is what that exact card actually sold for on average over the last seven days at Cardmarket, Europe's big card marketplace — prices are in euros because that is how it trades.
Two Tentacool cards can be worth wildly different amounts, and that is normal: they are different cards. Every set prints its own version, often at several rarities, and a rare version printed in small numbers can be worth a hundred times the common one. The code and number at the bottom of the card tell you which one you are holding.
The 7-day average is what the card actually traded at this week at Cardmarket. Read on 5 September 2026.
Our prices are for cards traded as they are at Cardmarket. Graded cards — the ones scored and sealed in a case by specialist companies — sell on a different market, and we do not measure that one.

There are also 3 Tentacool cards we are leaving without a price, and you deserve to know why. Cardmarket keeps those cards together under a single entry. The price sitting there is a real one. Trouble is, nothing tells us which of the cards it belongs to, so we hand it to none of them. The day each card gets an entry of its own, its price turns up here by itself.
What these cards have cost, day after day
We take every card's price down each day, and we keep all of it. Here is what that looks like for Tentacool cards.
Tentacool has 13 priced versions, and drawing every one of them would turn this into a page nobody can find anything in. The 5 dearest are here. The other 8 have no curve on this page, and their price for today is still in the table just above.
The decks that play it
None of the tournament lists we have read plays a Tentacool card right now. That happens: plenty of cards are collected more than they are played.
