How much is Rillaboom #84/70 worth?

Rillaboom #84/70 is a Ultra Rare Japanese card from Explosive Walker (2020) — today it trades at roughly $15.41 ungraded.

A PSA 10 copy runs about $35.97 and a PSA 9 about $11.25 — a 2.3x premium over raw, so condition and grading costs matter here. 96 copies have been graded to date, and 86% 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.
