Pikachu

Raw copies of this Pikachu have been shifting at £1,208 — the latest sale went through at that mark just recently — yet the cheapest ask on the market sits at £83.90, which tells you the asking price and actual sales are miles apart. With only 2 UK sellers listed, you're looking at a thin market, so if you're pricing to move stock you'll need to be realistic rather than hopeful about where this sits.

• CautionOnly 2 UK sellers, cheapest at £83.90. Thin market: price firmly, expect a slow sale.
• NotableRaw copies actually sell for £1,208 (10 UK sales in 90 days, latest £1,208 on 2 Oct); the cheapest ask is £83.90.
