Tap to open
Tentacool is one of those quietly charming water types that longtime Pokemon fans always seem to have a soft spot for, and this particular version, the 1st Edition #20 from the Japanese Undone Seal set, adds a nice bit of history to that appeal. If you are trying to pin down Tentacool value, the short answer is that it sits at the affordable end of the hobby, with raw copies going for $1, but that low price is exactly what makes it a fun one to track. It is a card built more for the joy of collecting than for chasing big money, and that is part of its charm.

The collector's take on Tentacool
Is Tentacool worth grading?
So is Tentacool worth grading? Here is the honest breakdown. A raw copy sits at $1, a Grade 9 moves up to $3, and a PSA 10 gem mint copy reaches $17, which works out to about 14.7x the raw price. That jump looks exciting on paper, but grading fees are real money, and by the time you pay to submit a card, add shipping, and wait for it to come back, you can easily spend more than the card is worth even if it comes back a 10. With only 18 PSA 10s recorded out of 49 total graded copies, gem mint is not a guarantee, so grading Tentacool really only makes sense if you already love the card, want it protected long term, or are grading it alongside other cards in the same order to make the cost worthwhile.
How rare is Tentacool?
Scarcity is where Tentacool gets genuinely interesting. Only 49 copies have been graded across all grades, and of those, just 18 have reached PSA 10. That is a fairly tight population for a card like this, and it tells you that clean, well centered copies from this print are not exactly sitting around in piles. When a population is this small, even modest price movements can shift quickly if demand ticks up, so the current value reflects a snapshot of a market that has not seen a huge volume of copies pass through grading yet.
Where can you pull Tentacool?
This is where PackSpy's own data comes in handy, since we track real pulls across pack opening sites rather than relying on guesswork. We have recorded Tentacool being pulled 23 times across collector-crypt, courtyard, and mnstr, with the biggest recorded pull value hitting $1,043, which shows just how much a single lucky rip can swing depending on the copy and its condition. It has shown up in packs like the Starter Pokemon Gacha Pack, Water Pack, Wildcard Starter Pack, Pokemon Starter Pack, and Wildcard 3: Inferno. Worth remembering though, opening packs is gambling, and most rips do not come close to that top number, so if you are chasing this card specifically, buying it directly on the secondary market is often the steadier route.
Questions people ask
How much is Tentacool worth?+
A raw, ungraded Tentacool 1st Edition #20 is valued at $1, a Grade 9 copy sits at $3, and a PSA 10 gem mint copy reaches $17. It is an accessible card value wise, which makes it a fun one for collectors who like the set without needing a big budget.
Is Tentacool worth grading?+
It depends on your goals. The PSA 10 price of $17 is about 14.7x the raw value of $1, but with only 18 PSA 10s out of 49 graded copies, hitting gem mint is not guaranteed, and grading costs can eat into any potential profit.
Why is the Tentacool 1st Edition #20 print worth more than the standard one?+
1st edition cards from Japanese sets like Undone Seal are printed in smaller numbers early in a set's life, which naturally makes them scarcer over time. That scarcity, combined with the low graded population of 49 copies total, is a big part of why collectors seek out this particular print.
