This is a nice ancient Iron Age copper brooch, dating to the 4th - 2nd century BC. It is intact with the original sprung pin, but missing the very tip of the catchplate where it curls over and wound have formed a wire that wrapped around the foot. However, the pin is still springy and the copper has a light green encrusted patina. The form is classed as a La Tene IB type, Cf Hattatt, R, 2007, A Visual Catalogue of Richard Hattatt's Ancient Brooches, Oxbow Books, Oxford p 288.
