Why this card

A top grade is worth €3511, about 16 times the €215 it costs to buy and send this card in. Of the 1,419 copies already graded, 2.5% came back that high. On average, one raw copy is worth €225 after grading. Scarce 10s keep the premium; average copies still pay.

One grade up

Each row buys the lower slab at the guide price and sells it on the next priced PSA rung. The leftover is what remains if the copy actually comes back there, after the PSA fee and about 10% to sell the new slab. Dirt on the surface can sometimes earn that one rung. Centering, corners, edges, and a crease cannot. The prices do not say which of those held this copy down.
