›How we work this out

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.

Near Mint 33 prices (TCGplayer), 100% of it from this card itself.

≈ means estimated: this card has no price of its own in that quality.
