This one's a bit of a ghost in the UK market—there haven't been any listings or graded sales here in the last 30 days, so the £40.14 price is sitting on Cardmarket with no local comparables to anchor it. That means if you're thinking of selling, you'll struggle to find recent UK evidence of what it'll actually move at, and if you're buying, you're essentially relying on a single marketplace's valuation.

• NotableNo UK listings or graded sales in the last 30 days. Cardmarket is the only reference.
