Where the Onix money is

Value is not spread evenly across the printings — the ranking below is by total tracked value, not by card count, the same measure as the most valuable Pokémon cards.

The top 5 of 31 Onix cards hold 83% of the $109 total. The remaining 26 share what is left, which is why a “complete Onix collection” in the collection tracker costs far less than the headline suggests until you reach the top row.

This is the median, not the average. Averaging the ratios gives 120×, which only 12 of 26 cards (46%) actually reach: a card worth a few cents raw with a three-figure slab produces a ratio in the hundreds and drags the mean above almost the whole set. The median is what a card in the middle really does, and it is the figure to take to the grading ROI calculator.

1 year is withheld: the weighted index and the basket total disagree over that window, which means the index was re-based rather than the cards re-priced. A number we cannot stand behind is worse than no number.

Collecting Onix cards

Onix has been printed in every era of the game, from 1999 (Base) to 2025 (Mega Evolution). The Vintage (1999–2003) era holds the most printings, 9 of the 31, and it holds the value too: $83, 76% of the total.

Most Onix cards are cheap to own: 27 of the 31 priced cards sit under $5 raw, the cheapest being the Onix, and the median card is worth about $0.58. 1 is worth $50 or more. A set-by-set Onix collection is a small-dollar exercise until the last card, which is where 54% of the total on this page comes from.

By rarity the printings split into 4 tiers, led by Common (23), Uncommon (3) and Rare (1). 26 of the 31 cards carry a PSA 10 price, the figure the grading section uses; those cards are worth about $0.44 raw at the median, against $1.01 for the 5 with no gem-mint price on file.

The grid filters by set and rarity and sorts by value, era, the PSA 10 gap or the 30-day move, so the cheapest Onix is one sort away (add the rarity filter for the cheapest holo); the by-set index above lists every card as text for when you know the number. Prices are CardTrack's blended raw value from real sold results, updated today.
