What Is Onix Worth?

Onix is a Common card from the Southern Islands set, card number 03/18. On PokeCardWorth we focus on one question — what is it actually worth — and at its current valuation, it carries real mid-range value and is worth keeping protected in a sleeve and top-loader.

Onix Value Breakdown

As of 2026, Onix (Southern Islands, 03/18) is worth around $35.80 in Near Mint condition. Condition drives the price hard: a Near Mint copy is worth about $35.80, while a Damaged one drops to roughly $11.71. The full condition ladder runs Near Mint $35.80, Lightly Played $27.53, Moderately Played $21.91, Heavily Played $15.38, Damaged $11.71 — so grading the condition correctly before you buy or sell matters more than almost anything else. A PSA 10 (Gem Mint) example is valued near $182.74 — about 5.1x the raw price, which is the single biggest swing in this card's value. PSA 9 copies sit around $55.00.

Is It Worth Grading Onix?

Grading Onix can pay off concretely: the gap between its raw value ($35.80) and a PSA 10 ($182.74) is about $146.94 — a 5.1x uplift before grading fees. Other graded tiers we track: PSA 9 $55.00, CGC 10 $399.00, BGS 9.5 $35.00. Grading is worth considering if your copy looks clean — the PSA 10 premium can comfortably clear the fee.
