If you've got a clean copy of this card, grading to PSA 10 is worth considering — they're selling at 5.2× raw value with 3 sales this week, putting the median at £83.42. However, the gap between a PSA 10 and a PSA 9 is steep at 3.1× (£83.42 versus £26.49), so only send in a flawless example. The cheapest UK ask has jumped 14.1% to £15.99, but that copy is flagged as MP condition, so a clean one should command a better price. PSA 10 medians have dropped 22.3% since the last crawl, from £107 to £83.42, though they're still shifting at roughly 2 sales per week.
