Live Now on eBay: 1st Edition Onix

What the card is actually being offered for right now. Every listing below is filtered to the genuine 1st Edition card — no repacks, mystery slabs, card skins, or multi-card lots. These are asking prices, not sold comps, so treat them as the top of the market rather than what copies are changing hands for. Buying through these links supports the site at no extra cost to you.

Which One Do You Have? The 3-Second Test

Most people who say “I have a 1st Edition Onix” don’t. Retail packs in 1999–2000 were overwhelmingly Unlimited printing — and that’s fine, it’s the same iconic card. The fast check, in order:

1. Right edge of the art box: a dark drop shadow = Unlimited or 4th Print. No shadow = keep going.
2. Left of the art box: a black “Edition 1” stamp = 1st Edition. No stamp + no shadow = Shadowless.
3. Bottom copyright line: ©1999-2000 = 4th Print. The font weight is the tiebreaker — thin text means an early print.

Onix is a Basic Fighting with 90 HP, illustrated by Ken Sugimori. Check centring first, then the border — that is where this card’s documented artifact sits.

The four printings of Base Set each have their own price and history: 1st Edition · Shadowless · Unlimited · 4th Print.

PSA 8 prices from PriceCharting sold-comp data, September 2026. Unlimited and 4th Print look nearly identical — the copyright year is the difference. Each printing is its own card with its own price and history; see every printing: 1st Edition · Shadowless · Unlimited · 4th Print.

About This Card and Set

Onix is card 56/102 in the English Base Set, a Common Fighting-type Basic illustrated by Ken Sugimori and released on 9 January 1999. This page covers the 1st Edition print: the stamped, shadowless-stock run Wizards of the Coast shipped from that January into roughly early March 1999, marked by the black “Edition 1” stamp beneath the artwork and by the thin HP font and absent drop shadow it shares with the unstamped Shadowless print.

For collectors the card is inseparable from Brock, the first Gym Leader in Pokémon Red and Blue, whose ace was an Onix, and from the anime’s fifth episode, “Showdown in Pewter City.” That fame carries a running joke: Onix is colossal in the fiction yet famously poor in the games, with a base stat total of 385 and an Attack of 45 — below unevolved starters. It is the standard example of a design betrayed by its stats, and the community has never stopped discussing it.

Within its era the card is the complete line. Onix was a stand-alone Basic in Generation I; its evolution, Steelix, arrived only with Generation II, so Base Set Onix was the end of the family for its time. The artwork stayed with the card through both reprints — Base Set 2 (#84/130) and Legendary Collection (#84/110) reuse the same Sugimori illustration.

How Rare Is This Card?

Read this card by its grade split rather than by a headline population. 21.1% of PSA-graded copies reach PSA 10, 9.0% come back grade 6 or below, and the rest land in between — which is what set the price ladder above. The odds column is the number that matters, because high-grade supply is what the market actually pays for.

Onix’s graded population is mid-sized and its Gem Mint rate is 21.1%, a fair ratio against a raw cost near $26.

PriceCharting population data, September 2026. The modern row is a combined PSA + CGC count; the 1999 row is PSA, the way it is normally quoted.

For scale, a comparable modern chase card converts to a gem grade at roughly 29%. Modern cards grade far better than vintage ones — not because they are better cards, but because a 1999 card was printed before grading was mainstream and then spent two decades in a binder.

Source: the PSA-only figures behind the Cards Worth Chasing ranking, September 2026. Two caveats stay attached to every population figure on this site. Graded counts are submission tallies, not unique cards — resubmissions inflate the total. And the census is a floor, not a final number.

Known Error Cards

Only one ink artifact is tied to Onix, and unlike most Base Set faults it belongs to the 1st Edition print. Elite Fourum’s English Base Set Master Misprint Guide lists a “Border Hickey Onix” — a gold border hair hickey recorded on 1st Edition stock and shared with Fighting Energy #97. A stray hair touching the gold border roller left a thin repeating mark. It is a printing artifact, not a design error: the card text itself is correct, and PSA and CGC do not recognise it.

There is a numbering caveat worth stating. That guide labels the entry “Onix (59)” — but Onix is #56/102, and #59/102 is Poliwag. Since the guide pairs the entry with Fighting Energy #97 and names Onix, the “59” is a numbering slip in the guide rather than a reference to a second card. Our Fighting Energy review records the same artifact.

What Makes This Card Collectible?

Onix is collected for nostalgia and a genuine 1st Edition artifact:

• Brock’s ace. The first Gym Leader’s signature Pokémon, on screen in episode five and in the games’ first Gym.
• A famous stat mismatch. Huge in the fiction, weak in the games — the hobby’s favourite design irony.
• A 1st Edition border hickey. The gold border hair hickey is documented on this print, shared with Fighting Energy #97.

Its counterpart is the Fighting Energy review; the Base Set hub covers the run.

Caleb's Collector Verdict

Onix is the set’s most nostalgic common, and one of the few whose documented artifact actually sits on the 1st Edition print.

People Also Ask

Is my 1st Edition Onix real or fake?
The 1999 Base Set cards are the most counterfeited in the hobby, and for a raw copy worth real money you cannot settle it from a photo. The checks that catch most fakes: the light test (a genuine card is essentially opaque — a faint dark core line between the layers; cheap fakes glow through), the stamp rule (a real 1st Edition stamp is crisp and sits under the ink, and counterfeiters add stamps to Unlimited cards — read it with the drop shadow and the 1995-99 copyright line, never alone), and the back (fakes perfect the front and neglect the Poké Ball, the blue tone and the repeated text). Above a few hundred dollars, a raw copy should get professional pre-authentication. The full fake-detection walkthrough covers all of it.

Should I grade this card?
Onix is a $26 raw with a 21.1% gem rate — best graded for the set rather than the spread. See Should You Grade Pokémon Cards? for the fee maths, and check a raw copy with the CardGrader scanner before sending it in.
