A practical guide to what actually drives a card's price.
Whether you've found an old binder in the garage or you're actively collecting Pokémon, Yu-Gi-Oh!, Lorcana, or One Piece cards, "how much is this worth?" almost never has a single answer — it depends on a handful of factors working together.
Card name alone tells you very little. The exact set, card number, and rarity/variant (see our rarity guides for Pokémon, Yu-Gi-Oh!, and One Piece) are what actually pin down value — the same character can have printings worth 50 cents and printings worth hundreds of dollars.
Even the rarest card loses significant value with wear. We grade using standard terms — Near Mint, Lightly Played, Moderately Played, Heavily Played, and Damaged — and the gap between Near Mint and Moderately Played pricing can easily be 30–50% on valuable cards. See our full Condition Guide for what each grade looks like.
Popularity moves independently of rarity. A card tied to a popular character, a competitively played deck, or a nostalgic set can hold its value — or climb — regardless of how "rare" its symbol technically is.
New set releases, reprints, and tournament results can all shift prices quickly in either direction. This is why quoted values are always a snapshot in time rather than a fixed number.
The only reliable way to know what your specific cards are worth is to have them identified and graded individually. If you'd like a straightforward, no-obligation quote on your collection, visit Sell Your Cards — we'll walk you through it.
