About pokemonmarketcaps
This site ranks PSA10 Pokémon cards by marketcap — the product of how many PSA10 copies exist times what one currently sells for.
Methodology
Marketcap = PSA10 population × PSA10 sale price.
Data We Collect
- PSA10 sale prices — current market value for each card, refreshed daily.
- PSA10 population counts — how many copies have received a PSA grade of 10.
- Total PSA grading volume — number of copies submitted across all grades, used to compute gem rate.
- Card metadata — name, set, card number, language, and era.
- Card images.
- Manual overrides — a small set of ultra-rare cards (e.g. Pikachu Illustrator) use direct auction sale prices when no regular trade signal exists.
Refresh Cadence
Snapshots refresh once daily around 13:00 UTC.
What's Not Here
1-year charts and long-range deltas are filling in over time as we accumulate more daily snapshots. Cards without a confirmed price × population match are excluded from the leaderboard until we can confirm a mapping.
