PSA 10 hasn't shifted in two weeks despite a median of £754.89, so don't spend on grading when raw copies are moving steadily—9 sales in 14 days with a median of £128.15. The cheapest listing at £125.50 is flagged as played condition, which matters because 67% of UK stock is played; a clean copy should command more. At £129.42 you're above the current market median, so watch for the next raw sale before deciding.
