How is this scored?

The composite score (0–10) blends signals across trust, set tier, era, liquidity, and price. The four sub-scores shown above (Liquidity, Scarcity, Era CAGR, Friction) describe each card across complementary axes; they share inputs with the composite but use different formulas. The Friction sub-score (added 2026-05-11) combines liquidity, price-spread stability, era maturity, and affordability minus a flat marketplace-fee proxy. The era-benchmark ROI numbers project returns based on the card's release era — they're not card-specific predictions. Limitations: the score is a relative ranking heuristic, not a forecast. Prices are snapshots and can drift between refreshes — always verify externally before buying.
