What makes a Pokémon card valuable? Scarcity is only part of it

Scarcity is part of what makes a Pokémon card expensive, but it isn't most of it. Across 12,423 cards, rarity and age explain 34% of the price differences we could account for.^[1] The Pokémon on the card and its set explain 61%.

The scarcity idea makes sense on its face. The cards people chase in packs are the hardest to pull. Old cards from sets nobody opens anymore keep getting harder to find. Low population counts get quoted in listings like a selling point.

And it's partly right. Rare cards do tend to cost more than common ones. The catch is that rarity on its own decides less than the Pokémon and the set do. Among cards that are equally hard to pull, prices still spread out a lot depending on which Pokémon is on them.

The Pokémon on the card is the biggest single reason, and the set is close behind. Those two are really measures of demand, and together they explain 61% of what our five things account for. Rarity and age, our stand-ins for scarcity, explain 34%.

Here's how we measured. We took every English card worth $5 or more on TCGplayer at the end of September 2026 and asked how much of the gap in their prices five things explain: the Pokémon, the set, the rarity, the age and the art style. Some of those overlap, so each one's share is averaged over every order they could be added in, which is the fair way to split them.

One thing to keep straight. These shares are of what the five things explain together, not of the whole price. Together they explain 52% of the price differences between cards. The other 48% comes from things this comparison doesn't capture.

Art style explains the least of the five on its own, at 5%. It overlaps with rarity (a special illustration rare is both), and that overlap is split by the same averaging as everything else.

Yes, a lot. Hold rarity steady and the Pokémon on the card still swings the price hard.

Take the top-rarity cards from Sword & Shield on: special illustration rares, secret rares and the like. There are 503 of them in the comparison, and the typical one sells for $19.51. Every one of them is about as hard to pull as a modern card gets. Yet the typical Charizard among them costs $209, 11× the typical top-rarity card.

Gardevoir, Mew, Pikachu and Mewtwo round out the top five. Same rarity tier, same scarcity on paper, very different prices. What separates them is how many people want that Pokémon.

A fair warning: these groups are small. The Charizard figure rests on 7 cards, and Gardevoir's on 6. Read the ranking as a clear pattern, not a precise price list.

Scarcity does matter, just less than demand. Rarity alone explains 24% of what the five things account for, the third biggest single reason after the Pokémon and the set. Age adds 10%. That's a real effect, and anyone who says rarity means nothing is wrong too.

Here's what this data can't tell you. Graded population counts aren't in it. Rarity and age are how we measured scarcity, so this doesn't test whether a low pop PSA 10 sells for more than one with lots of copies graded. Pop counts could carry weight that rarity and age miss, and some of that might sit in the 48% left unexplained.

What the data does show is that among cards of the same rarity, the Pokémon matters more than pull rates would suggest. Scarcity helps a card's price. Demand does more of the work.

In the past they did, but that's a separate question. Everything above is about why a card costs what it does today. What a card did after someone bought it is about returns.

We tracked a group of fan favorites: Charizard, Pikachu, Mewtwo, Mew, Gengar, Lucario, Rayquaza, Eevee, Vaporeon, Jolteon, Flareon, Espeon, Umbreon, Leafeon, Glaceon, Sylveon. Over one-year holds since late 2022, the typical one returned +8% after fees, tax and shipping. Those returns count the marketplace's fee, shipping both ways, a small storage cost and tax on any profit.^[2][3][4] Every other Pokémon of the same rarities returned −5%. That's across 4,649 fan-favorite card-months and 16,362 others.

Those are typical results from past prices. They say fan favorites held up better over that stretch. They don't say any particular card will rise, and nothing in this study forecasts prices.

Ask who wants the card before you ask how rare it is. A secret rare of a Pokémon few people chase is still a card few people chase.

• Start with the Pokémon. It's the biggest single reason for price in this data.
• Then the set. Some sets carry more demand than others, and that shows up in prices.
• Treat rarity as a boost, not the whole story. It counts, but it explains less than the Pokémon and the set do.
• Be careful with "low pop" pitches. That's a scarcity argument, and pop counts weren't tested here.
• Leave room for the unknown. These five things leave 48% of the price differences unexplained.

If you want to see how this plays out in your own collection, Pokelit prices English and Japanese cards every night from TCGplayer prices, shows graded prices from eBay sales where slabs have sold, and keeps a binder that tracks value. Here's what the app does. For an honest record of how the model's picks have fared, the scorecard locks them in each month and scores them in public a year later, win or lose.

None of this tells you to buy or sell anything. It's a picture of how prices line up today, not a guess at where they go. More myth checks like this one are on the blog.
