There's no UK market activity to speak of on this card in the last 30 days—no listings or graded sales—so you're looking at Cardmarket as your only recent reference point. That thin data means pricing is harder to pin down than it would be with a more active card, so if you're selling, you'll want to watch comparable copies closely before committing to a price.
