Sealeo #promo is a Uncommon Japanese card from Secret of the Lakes (2007) — today it trades at roughly $4.00 ungraded. Across the 2 printings we track, copies run anywhere from $1.95 to $4.40 depending on the version you're holding.
Grading changes the math on this one: a PSA 10 is valued around $44.20, roughly 11.1x the raw price. 2 copies have been graded to date, and 100% 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.
