How to read this page
- % change is the median sale price now vs N days ago, deduped across printings.
- We require ≥3 sales in the window before a card is eligible — single-sale spikes don't make the cut.
- Cards under $1 are excluded so the list reflects collectible-tier movement, not chase-rare bulk.
- Refresh: every 6 hours.
