How much is Seaking #21/109 worth?

As of November 5, 2026, Seaking #21/109 from Ruby & Sapphire sells for around $1.67 in raw, ungraded condition.

Grading changes the math on this one: a PSA 10 is valued around $45.00, roughly 26.9x the raw price, while a PSA 9 sits near $37.31. 64 copies have been graded to date, and 25% 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.
