Price spectrum

Population & rarityHow Lugia's graded copies are spread across grades. Each bar is the number of copies graded at that grade; the percentage is that grade's share of the total graded population. Fewer copies at a grade = scarcer = a scarcity premium.

Relative valuation vs. indexBoth series are indexed to 100 at May 17, 2026, the index’s inception date, not the start of the selected range. A divergence means the card has outperformed or underperformed the index since then, by exactly the percentage-point gap.
