3 questions answered
Q.01
Is Professor Sycamore from Steam Siege a good investment?
We track prices, not provide investment advice. The Chase Index rank and price history above show how collector demand has moved since we started tracking this card.
Q.02
How is the market price determined?
We pull daily snapshots of the market price - the median of recent Near Mint sales. The current figure reflects the Holofoil variant.
Q.03
What does the Chase Index rank mean?
The Chase Index ranks cards on a composite score: 15% market price percentile, 35% upward-only 7-day price move, 30% rolling 30-day community chases, 20% recent page views. The global index is restricted to cards priced ≥ $5 and, for now, excludes vintage cards (pre-2004 sets), reverse holofoils, and Commons; per-set and per-tag rankings include every card. A card near the top leads on multiple dimensions.
