Don't grade this card unless it's flawless—a PSA 10 is worth 8.8× a 9 (£162 versus £18.48), but PSA 10 copies haven't shifted in two weeks, so you'd be throwing money at grading fees for stock that won't move. Half of the last eight PSA 10 sales went through as accepted offers rather than at asking price, so even the graded copies need negotiation room to find a buyer.
