There's a sharp gap here: raw copies have actually sold for £62.40 in the last 90 days (two sales, most recently at that price in early October), yet the cheapest ask sitting on the market is £26.70. With only two UK sellers listed, the market is thin enough that you'll need to price carefully and be prepared for a slow shift at the higher end.

• CautionOnly 2 UK sellers, cheapest at £26.70. Thin market: price firmly, expect a slow sale.
