The market's all over the place on this one: Cardmarket's £159 trend bears no relation to the 9 UK asks, which range from £31.90 to a £77.85 median, so price to the asks. The card's jumped 53.2% in a week against a 30-day gain of 34.9%, which looks like a spike rather than settled demand—sell into it or sit tight for a pullback. Raw copies actually sell for around £80.49 (30 sales in 90 days, moving at 3.5 a week), so that cheapest ask at £31.90 is flagged as played condition and genuinely undercut; a clean copy will fetch more. Most UK stock is played (57% of listings), so a Near Mint copy is the scarce thing here, and don't bother grading unless it's flawless—a PSA 10 sits at £562 against £136 for a 9, which is a 4.1× gap with zero sales in the last fortnight.
