Every now and then an object defies positive identification. One such example is this folded lead item, the fold being along the straighter edge, that is struck on both sides with a circular punch.

The question is whether the folded nature of the piece is intended to be a seal, perhaps trapping a, now lost, chord in the fold. Alternatively this may be a trial sttrike in soft lead, folded either before or after striking.

Illustrated on plate 2, images 1 to 4, the item with Carausius on one side and a representation of Pax on the other is postulated as being a seal, citing as comparanda British found seals of the later third century and/or early fourth from coin, or coin type, dies (RIB 2, 2411.20-21 and 2411.32.
