This one's dropped 11.1% this week and 24.2% this month, so if you're holding stock you'll want to think about listing now or waiting to see where it settles. It's already at its 30-day low of £130, down from £172 earlier in the month. The graded market is in freefall too—PSA 10 medians have fallen 41.7% from £377 to £220—and three of the last four sales shifted at accepted offers rather than asking price, which suggests room for negotiation at the upper end. Raw copies are actually moving at £78.70; there have been two UK sales in the last 90 days at that level, with the latest in mid-September.
