File:Possible brooch (FindID 96217).jpg

English: An incomplete late Anglo-Saxon or Viking Age copper-alloy trefoil possible brooch, with most of one arm missing due to an old break. It measures 40mm by 25mm (the latter measurement is across the incomplete arm), and is worn, each arm is c15mm in width.

It is flat and cast and the front face has simple decoration with a central triangle delimited by border grooves, each arm or foil is roughly rectangular in shape with a rounded terminal and has two parallel border grooves.  Within these there is a foliate design depicting what appears to be a single leaf with jagged V-shaped notches along its edges and a central longitudinal groove.
 

  
On the reverse there is a single incomplete integral lug which is set near the edge of the object between one of the complete and the incomplete foil.  Other scars from missing lugs (possibly pin lug, catch-plate and chain-loop) would be expected but cannot be seen, it is unclear if this is as they were never there, hence making it more likely that this object is a harness fitting or even a pendant, or because they have dissappeared due to wear. 
 

Trefoil brooch fragments are known from both Norfolk and Suffolk with stylised leaf decoration, sometimes cast. A complete example has been found in Wymondham, Norfolk, see NMS-10A1E1. This example may have Scandinavian origins and is most likely to be circa 9th century in date.
