The cheapest copy has been listed at £32.00 for 7 days without moving, so undercutting it should shift stock first. That asking price is for a played copy, so a clean example can command more money—92% of UK stock is played, which makes Near Mint scarce here. UK sellers are asking 634% over Cardmarket trend, which tells you where the market sits, though the actual price is £4.36.
