The cheapest copy on the market has been sat for 13 days at £39.85, so you'll need to undercut that to shift it first. Raw sales over the last 90 days show 20 UK transactions averaging £36.24—the latest went for that exact figure on 3 October—which sits well below the current asking prices. Grading to PSA 10 barely moves the needle, pushing the median only 1.06× higher, so it's not worth the cost and turnaround time here.
