How much is Onix #42/112 worth?

A raw copy of Onix #42/112 (FireRed & LeafGreen, 2004) is worth about $2.82 right now, based on the latest market data from November 4, 2026. Across the 2 printings we track, copies run anywhere from $1.49 to $499.58 depending on the version you're holding.

Grading changes the math on this one: a PSA 10 is valued around $151.00, roughly 53.5x the raw price, while a PSA 9 sits near $125.49. 119 copies have been graded to date, and 13% 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.
