1lb bar. 500-300BC. 327grams. Italy mint. Aes Grave. Crawford 000/03 Aes Signatum. Obverse: Cast 1lb bar, no design. Reverse: copper bar, 327g. Rare.
Precisely 1 Roman pound - 327 grams. There's some loss of weight due to flaking which likely account for another 20 or 30 grams, but in round terms this was a 1 pound bar, whole and unbroken thus not an accidental fragment. No markings.
