Frequently asked
Which Onix card is worth the most?
The most valuable English Onix card we track is Onix from Southern Islands (#3) at £40 ungraded. No Onix card reaches £100 ungraded.
How many Onix cards are there?
Our English catalogue holds 32 Onix cards across 30 sets, from Base Set (1999) to Mega Evolution (2025). Other languages are on each card's own page.
Is it worth grading a Onix card?
Grading costs from about £12 a card in the UK, so it pays only on a card worth well above the fee in clean condition. None of the 32 Onix cards with a value reaches £50 ungraded, so a grading fee would cost more than the card on most of them. Scan yours and the scanner says whether to grade it, with the expected money.
A quick word on the figures: “market price” is what an item actually sells for in the UK right now, not an inflated recommended price, and we only count plausible live prices, so one mispriced listing cannot skew the order. Prices shift through the day, so a deal near the top can move quickly.
