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 pays off: PSA 10 brings €248.62 more than ungraded, after commission and about €25.00 to submit. Whether the card grades that high, nobody knows in advance.
