You won't find this card listed anywhere in the UK right now, so the £15.14 price sits without local comparison—Cardmarket is your only reference point for where it's trading. That lack of recent UK activity means you're relying on European pricing to gauge whether it's fairly valued, which is worth keeping in mind if you're thinking of buying or pricing your own copy.

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