How is this scored?

The score (0–10) ranks this card against every card we track, using what our price history since 2021 shows actually separates cards that beat the market: the era’s track record, whether it is a popular Pokémon, special card types, and a recent price spike. The same score orders the Leaderboard and sets the grade letter. It compares cards; it does not forecast a price.
