With only one UK seller and a thin market, you'll need to price firmly and be ready for a slower sale. The cheapest listing at £59.99 is graded LP, so a clean copy should command more—raw copies have actually sold for £139 over the last 90 days, with the latest at that level on 25 September. That's a significant gap between the asking price and recent sales, worth bearing in mind when you're deciding where to pitch.

• CautionOnly 1 UK seller, cheapest at £59.99. Thin market: price firmly, expect a slow sale.
