This is a nice medieval bronze heraldic brooch, dating to the 13th - 14th century AD. It is cast in bronze with a quatrefoil shape plate, the back retains part of the brooch fittings for a pin. The design is of a Rampant lion of a shield, flanked with three wyverns (dragons).
A rare example, interesting!
