How much is Basic Water Energy #331 worth?

Basic Water Energy #331 is a Promo Japanese card from Sword & Shield Promos (2019) — today it trades at roughly $0.40 ungraded.

Grading changes the math on this one: a PSA 10 is valued around $34.99, roughly 87.5x the raw price, while a PSA 9 sits near $3.88. 31 copies have been graded to date, and 45% of them came back a 10 — worth knowing before you pay grading fees.

Prices on this page refresh nightly from live TCGplayer market data and are cross-checked against actual sold prices, so a single inflated listing never becomes "the price". The chart above has the full history.
