We rank by popularity — how coveted a card is — not by price alone. A card rises on its iconic standing (flagship rookies, on-card autographs, and marquee inserts), its scarcity (low serial numbers and true one-of-ones), and collector demand, with market value as a strong signal. The most expensive card isn't always the most popular.
Every list is checked against several sources before it goes live. The facts — how rare a card is, what it sells for, which versions exist — come only from card checklists, price trackers, and real sold listings.
What the community is chasing shapes how we order the list, but it never counts as a fact on its own. It tells us about demand, not whether a card truly belongs at the top.
We only call a card's rarity confirmed when the maker officially publishes the number. Otherwise we label it an estimate — and we never make a number up.
Each card photo comes from the eBay listing its button points to, so you're always seeing a real card that's actually for sale — credited to that listing, never taken from the card maker.
