This source names the grade but not the company. A 9 from PSA is not a 9 from CGC, so it stands on its own.

Grade	Price	Factor	Origin
Grade 10	≈ €63.55	×2.45	Estimated
Grade 9.5	≈ €41.76	×1.61	Estimated
Grade 9	≈ €85.51	×3.30	Estimated
Grade 8	≈ €20.88	×0.80	Estimated
Grade 7	≈ €18.16	×0.70	Estimated

On paper grading pays off: PSA 10 brings €413.84 more than ungraded, after commission and about €25.00 to submit. Whether the card grades that high, nobody knows in advance.

›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 18 prices (TCGplayer), 100% of it from this card itself.

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