Every Hisuian Basculin card we price, most valuable first. Prices are what copies actually sold for, updated daily.
The same Pokemon is also printed as Basculin, priced separately because the game treats them as different cards.
What a Hisuian Basculin card is worth
The most valuable Hisuian Basculin on this list is Hisuian Basculin from Sword & Shield Promo Cards at $0.37£0.28€0.33, and the 4 priced copies across 4 sets are worth $1£1€1 together. Most of that sits in a handful of printings: the older the set and the scarcer the print run, the wider the gap to the rest.
Hisuian Basculin is printed in Japanese as well: 6 cards across 3 sets, the most valuable of them Hisuian Basculin (Mirror Holofoil) from VSTAR Universe at $0.57£0.43€0.50. Switch the list above to Japanese to read those, or to Both to rank the two catalogues against each other.
reverse holo printings are priced separately from the standard card, because they do not trade at the same money.
If you are trying to identify which Hisuian Basculin you have, the set name is printed on the card and the collector number sits in the bottom corner. Open the card here and the page carries every printing of it, the graded prices, and whether grading the copy is worth the fee. Sets to start with: Sword & Shield Promo Cards, Lost Origin, Prize Pack Series Cards.
