Gengar & Mimikyu GX

The cheapest copy has sat unsold 7 days at £149.99—undercutting it is your best bet to move first. That one's flagged as HP condition, so a clean copy can ask more; raw copies have actually sold for £283 over the last 90 days, with 5 sales in the past fortnight alone. Be warned though: a PSA 10 is worth 4× a 9 (£1,624 versus £402), so only grade if you've got a flawless example. UK asks span from £150 to £271, with most sellers pricing well above what's shifting.
