The cheapest copy has been sitting unsold for 7 days at £14.22, so undercutting it should get you moving first. That said, it's flagged as LP condition, which means a clean copy can command more money. Bear in mind that PSA 10 median has dropped 14% recently from £105 to £90.59, and there's a brutal gulf between grades here—a PSA 10 is worth 8.3× a PSA 9 (£90.59 versus £10.95), so only grade a flawless copy.
