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 CGC 10 does not cover commission plus the roughly €25.00 to submit.
