Slowbro

There's no UK market activity on this Slowbro to speak of—no listings or graded sales in the last month—so the £33.09 price sits on Cardmarket alone with nothing local to anchor it against. That makes it a tricky one to value if you're buying or selling here, since you're relying entirely on the European market's read rather than what collectors are actually paying down the road.

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