I went looking for a site that could tell me which Pokémon cards are actually worth buying. Price guides everywhere, recommendations nowhere. So I built one that treats cards like stocks: 29M+ historical price points across 17,000+ cards power a composite investment score for every card, ranked leaderboards filterable by budget, full price history, and a grading calculator that nets out fees. Prices are real European market values. Scores and leaderboards are free.
