File:Anglo-Saxon Nummular Brooch (FindID 407867).jpg

English: An incomplete lead disc or nummular brooch of late Anglo-Saxon date. It is missing its iron pin due to old reaks but is otherwise intact. The brooch is flat, disc shaped in form and with moulded decoration on the front face. This comprises a cross pattee with central pellet at the centre of the brooch. An inner border formed from double parallel lines with numerous short vertical strokes surrounds the central motif, with a second similar band of decoration forming a border around the outer edge of the brooch. Between the inner and outer borders there is a band of pellets. The flat back face of the brooch is undecorated but has an integrally cast pin lug that is semi-circular in form and preserves the remains of the iron pin. At the opposite end of the reverse face is an integral catchplate that is rectangular in form with folded outer edge creating an oval shaped aperture. Thsi brooch measures 32.22mm in diameter, 1.69mm in thickness, and weighs 14.63g.

Lead disc brooches such as this are known from Suffolk (see for example SF-CBDDE0, SF-88E700, SF-C76146) and elsewhere (for example NLMS5282 or NMS-895D26). They are termed nummular due to the fact that the decorative elements on the front face are ultimately derived from coins and often have rings of pellets, around a central 'coin' motif. In the current example this has become abstracted/debased as is often found on brooches of this type. This brooch is likely to date to the late Anglo-Saxon period, c.900-1100 AD.
