File:Lead disc or nummular brooch of late Anglo-Saxon date (FindID 559603).jpg

English: An incomplete cast lead disc or nummular brooch of late Anglo-Saxon date. Approximately one quarter of the brooch survives intact, the remainder now missing due to old breaks. The surviving fragment is flat, with some post-depositional corrosion and was probably originally circular in form. On the back face is an integrally cast flat, rectangular catchplate that is now flattened against the back face of the brooch, the corresponding pin lug now missing due to old breaks. The front face of the plate has moulded decoration that may be considered broadly nummular in form although possibly now abstract from coin types proper. It comprises an outer double border containing multiple vertical strokes or lines. Extending from the border towards the centre of the plate are two curving, U-shaped bands decorated with multiple transverse strokes or lines. Between the two bands is a series of pellets that extend towards a flaring central(?) panel. The precise form of the original decoration remains uncertain, and the curving bands might be interpreted as shoulders for a bust or equally plausibly as elements of an abstract (symmetrical?) geometric motif. The entire fragment measures 17.06mm in surviving length, 28.43mm in width, 5.77mm in thickness (including lug; 1.15mm at plate) and 4.38g in weight.

Lead disc brooches such as this are known from Suffolk (see for example SF-758F83, SF-408304, SF-CCF226, SF-CBDDE0, SF-88E700, SF-C76146) and elsewhere (for example LEIC-D40622, NLM5282, NLM4639 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 is more abstract although potentially the incomplete central motif may have originally been more coin like. The current example is likely to date to the late Early-Medieval period, probably in the 10th or 11th centuries AD.
