Is Walrein 15/101 worth anything?

Copies of this card currently trade at around €20.64 on Cardmarket, assuming near-mint condition. The price you'll get in the UK depends mostly on condition: check the corners, edges and surface, and whether the artwork is well centred. Damaged cards sell for much less, while professionally graded copies in top condition can sell for far more.

To be sure you have the right card, match the set symbol and the number 15/101 printed at the bottom of your card. There are 13 different Walrein cards, so the number matters. Then compare completed eBay UK listings — sold prices, not asking prices — for copies in similar condition.
