The cheapest copy has been sat unsold for 7 days at £10.80, so undercut it if you want to move first. Cardmarket's trend at £43.06 looks unreliable against 30 UK sellers ranging from £10.80 upwards—price to the asks, not the trend. Raw copies are actually shifting at a median of £37.10 (25 sales over 90 days, about 2 a week), which sits well above that rock-bottom ask, but grading won't help: PSA 10s haven't sold in a fortnight. The cheapest ask has collapsed 49.8% in one crawl (£21.50 down to £10.80), so watch for further movement before you commit.
