Down 18.8% this week and 18.8% this month, so if you're holding this one, now's the time to decide whether to list or sit tight for a floor. The cheapest copy at £135.96 is flagged as HP by the grader, so a clean example can command more—and that matters, because 71% of the UK stock is played (5 of 7 known), making Near Mint the scarce grade. UK asks range from £136 to £363, with the median at £362.56, so that cheapest listing is 63% under the middle; the foil trades at 2.2× the regular printing (£12.34 versus £5.57), which tells you there's still appetite for the better versions.
