Tentacruel

The market's thin with only 2 UK sellers, so you'll need to price carefully and expect a slower sale. The cheapest listing at £13.47 is graded LP—a clean copy should command more. That said, raw copies have actually sold for £3.08 over the last 90 days, so there's a substantial gap between what's asking and what's moving. This pokeball printing sits 175.6× higher than the plain version at £0.18, which reflects the rarity you're working with here.
