During excavations in 1971 at New Kiln Road, Lexden (ECC406), Late Bronze Age, Iron Age and Roman features were discovered. The Bronze Age features consisted of one short slot, a small pit and 33 post-holes. Nineteen of these features produced pottery which was exclusively flint-gritted (see MCC1355). Features which belonged to the Late Iron Age and Roman periods included two substantial pits, a small dump of moulds for coin flan, a shallow depression, a complex of two parallel slots and two small depressions. These features all contained pottery typical of the Late Iron Age and early Roman pottery from the Sheepen site (see ECC328).
There was a total of 438 fragments of coin-flan moulds and several large pieces of partially vitrified clay from a furnace all resting on the top of the cover loam. 52 more fragments of mould were found in the backfill of a 1930's excavation trench and 125 fragments were recovered from the cover loam or the brown sandy loam which sealed it.<1>
