The typical Onix card costs $2.70. Across the 29 of them that carry a price, the cheapest is $0.12 and the dearest is $132.50 — Onix 84, at $132.50. That spread is why the group price is a starting point and not a valuation of any one card.

The middle step counts every card that records a Pokédex number, including Pokémon too small to have a page of their own. That is why its figure is larger than the totals on the Pokédex number list, which only counts the groups it can open.

Onix Pokémon cards at a glance

  • What this group is. 30 cards share the Pokédex number Onix. The Pokédex number ties every print of the same Pokémon together, whatever the set is called and whatever extra words the card name carries. Grouping by the number keeps prints of one Pokémon in one place instead of scattering them by name.
  • What they cost. The typical card is $2.70. Across the 29 priced cards the range runs $0.12 to $132.50.
  • Where it stands. No. 157 of 206 Pokémon by typical price, with 49 of them cheaper.
  • What the cards are like. They average 99 HP and 50 maximum damage, and are most often weak to Grass.
  • What is listed below. Every one of the 30 cards that carries a price, each with its own price page. The other 1 are counted in the total but have no published price, so they are not listed.
  • When it was read. Every figure on this page comes from the archive as it stood on August 14, 2026.

Which Onix cards share a name across several printings?

29 of the 30 cards listed above are reprints of just 2 names. Buying by name alone is how people end up with the wrong printing, because these share a name but not a set, a rarity or a price.

How Onix Pokémon card prices are spread

One number cannot describe a group whose cards run from a few dollars to several thousand. These four points and the bands under them show the shape of it.

An average hides the shape of a group. These four points say where the money actually sits among Onix cards.

A typical Onix card$2.70medianThat is 2.0% of the dearest single card at $132.50. "Onix cards are expensive" is a story about one card.
The cheapest Onix card$0.12Paradox Rift #90That is 4.4% of the typical price, so this group has cards you can buy for pocket change.

This page carries no graded prices for Onix cardsPaid data A graded copy can be worth several times an ungraded one, but population counts and graded sale prices are only sold commercially.Rather than print a guess, the column is left out — every price here is for an ungraded English card.
The counting sections and the price sections do not share a denominator. This group holds 30 cards, but only 29 of them carry a price. Every figure about money on this page — the typical price, the quarters, the bands, the ladder — is counted on those 29, while every figure about how many cards exist is counted on all 30.

How much HP and damage Onix Pokémon cards print

An average hides the shape of a group: it reads the same whether every Onix card prints the same number or they run from one end of the scale to the other. These five points show which of the two is happening.

Standard and Expanded are the two tournament formats. A card leaves Standard when its set rotates out, so this share moves each year while the card itself does not change.

Each track is the whole of the 30 Onix cards on file, so the empty part of a bar is the share the answer does not cover.

The four rows are not slices of one whole — a card can be legal in Standard and carry an Ability at the same time, so the bars are read one at a time against the group.

Which Onix Pokémon cards moved most this year

The group line is made of single cards, and they do not all move together. These are the two ends of that spread over the last twelve months.

Biggest risers over 12 months

Biggest fallers over 12 months

Counted on the 16 cards that carried a price on both the first and the last reading, so a card that only appeared recently is not in here.

The cheapest Onix Pokémon cards you can buy

Every list on this page so far has run from the top down. This one runs from the bottom, because the first question of anyone starting a Onix collection is what it costs to get in.

The 6 cheapest Onix cards on file

Cheapest first. Each card opens its own price page. Prices exclude shipping, which on a card at this level is usually more than the card.

These six together cost $1.44, against $132.50 for the single dearest Onix card. The two ends of the same group sit 1,104× apart, and both of them are correctly described as "Onix".

How Onix compares with the other Pokémon

A price on its own says nothing until you know what the group next to it costs. This is where Onix sits among the 206 Pokémon on file.

"Which Pokémon is the most expensive" has three different answers depending on what you measure, so this section keeps them apart.

Ranked by its single dearest card, Onix is number 124 of 206 Pokémon, on Legendary Collection #84 at $132.50. By card count it is number 107, and by the price of an ordinary card number 157 — three different answers to "is it the most expensive".

Onix Pokémon cards — frequently asked questions

How many Onix Pokémon cards are there?

There are 30 Onix cards in this archive, and 29 of them carry a price. The Pokédex number ties every print of the same Pokémon together, whatever the set is called and whatever extra words the card name carries. Grouping by the number keeps prints of one Pokémon in one place instead of scattering them by name.

How much is a Onix Pokémon card worth?

The typical one costs $2.70. Across the 29 priced cards the range runs from $0.12 to $132.50, so the group price is a starting point rather than a valuation of any one card.

What is the most expensive Onix Pokémon card?

Onix 84 from Legendary Collection, at $132.50. It is 49× the typical price of the group.

Are Onix Pokémon cards rare?

By price they rank No. 157 of 206 Pokémon, with 49 cheaper than this one. By size the group holds 30 of the 20,444 English cards on file, or 0.1%. Those two together are what "rare" usually means in practice — few of them, and dear because of it.

Do all Onix Pokémon cards have a price?

No. 29 of the 30 carry a price on file. The rest have never been listed at a price this archive could read, so they are counted in the card total but left out of every price figure rather than guessed at.

Where can I see every Onix Pokémon card?

The list on this page holds the 30 most expensive of them, dearest first, and each card opens its own price page. The remaining 0 carry no published price, which is why they are not drawn.

How often are Onix Pokémon card prices updated?

Prices are read once a day from public marketplace listings. The figures on this page were read on August 14, 2026. Which cards belong to this group comes from openly published card files and changes only when a new set is added.

Are Onix Pokémon cards going up in value?

Over the last 11 months the typical Onix card rose from $1.36 to $2.70, a change of +98.5%. That is the middle of the whole group, so it describes an ordinary card of this kind rather than the headline one at the top.

How much does a cheap Onix Pokémon card cost?

One in four Onix cards costs $0.43 or less and the cheapest on file is $0.12. Three in four cost $10.00 or less, so the cards past that point are the exception rather than the rule for this group.

Which Onix Pokémon cards are worth the most?

Sorted by rarity, Uncommon is the dearest kind of Onix card: 3 of them are on file and the middle one costs $2.70. The table on this page lists every rarity in the group beside its own typical price.

What is the highest HP on a Onix Pokémon card?

The highest printed HP among Onix cards is 200, and the lowest is 60. The typical one is 95 HP, with half of them between 90 and 110 — figures counted from the 30 cards in this group that print an HP value.

Are Onix Pokémon cards legal in tournaments?

4 of the 30 Onix cards are legal in Standard today and 14 in Expanded — 13.3% and 46.7% of the group. A card leaves Standard when its set rotates out, so this share moves each year even though the cards do not change.

What are Onix Pokémon cards weak to?

Most often Grass — 25 of the 30 Onix cards that print a weakness take double damage from it, with Water next at 5 cards. Weakness is printed per card, so the group tendency is a guide and the card itself is the answer.

Are old Onix Pokémon cards worth more than new ones?

Not simply by age. Among Onix cards the 2000 printings sit at a typical $4.86 and the 2019 ones at $1.71, while the dearest year of all is 2000 at $4.86. Print run and demand decide it, not the date on its own.

Which Onix Pokémon card rose the most this year?

Onix 92 from Diamond & Pearl, which went from $1.80 to $10.00 — a change of +455.6% between August 14, 2025 and August 14, 2026. It is one of 16 Onix cards that carried a price on both days.

Before you rely on these figures

Note: Prices on this page are asking and market prices for ungraded English Onix cards, taken from a daily snapshot of public marketplace listings read on August 14, 2026. They are not offers, they exclude shipping, duty and marketplace fees, and they move. Counts cover only the English cards this site holds on file. Graded prices, population counts, sealed product values and pack odds are not published on this site because no free commercial source provides them.
