The PSA 10 median has dropped 15.8% since the last crawl, falling from £224 to £189, so don't expect recent asking prices to hold. The gap between grades is brutal here—a PSA 10 sits at £189 while a 9 trades around £27.19, nearly 6.9× cheaper—which means grading is only worth doing on a genuinely flawless copy.
