Nobody is selling this card on Trademeup right now. The market price beside it is a reference from other venues; it is not something you can buy here.
The Trademeup index is the median of real sales on this marketplace (7/30 days, per condition). External source curves are shown for comparison.
Market pressure
Ungraded, by condition
Graded, by company and grade
Every number here is the market price above, times what that quality is worth. We measure that multiple on this card, and where there are no prices for it, we use the going rate across the whole catalogue.
≈ means estimated: this card has no price of its own in that quality.
On paper grading does not pay off: even PSA 10 does not cover commission plus the roughly €25.00 to submit.
