The cheapest copy has been sitting unsold for 8 days at £4.47, so undercutting it will be needed to shift stock first. UK asks are running well below the Cardmarket trend at 38% of it, which suggests the trend data is stale and you should trust the asks over the price. Most of the listings here are played copies—6 out of 8—which means a Near Mint one would stand out from the crowd. The asks themselves span a wide range from £4.47 up to £12.90, with the cheapest sitting 65% below the median, so there's real scatter in what sellers think this card is worth.
