Belt plates, armour hinges, and the hardware of the legions.
Roman soldiers shed hardware wherever they served: belt and apron mounts (often tinned or enamelled), lorica segmentata fittings (hinges, buckles, tie hooks in brass), scabbard slides and chapes, pendant harness decorations, and distinctive armour-piercing artillery boltheads.
Military belt plates run to recognisable series — openwork, niello-inlaid, enamelled — datable within the imperial centuries. A scatter of such fittings plus coins can mark a fort, camp, or battle line; single finds mark roads and veterans' farms.
Check for tinning (silvery surface patches) and enamel in cells; measure and photograph both faces. Fittings identify best against published military-equipment corpora, so a clear outline photo goes a long way on the board. Findspot patterns matter — record each piece separately, precisely.
