Unown

This is a fresh release—the set's only just over two weeks old—and you should expect prices to drift lower over the next couple of months as the market settles. At £0.58 it's a common card in a new set, so don't rush to buy or sell thinking this is a floor price; there's usually more downward movement to come in the first three months.

• CautionSet is 2 weeks old. Prices typically fall for the first three months after release.
