(neuter form of the late Latin miliarensis
"pertaining to a thousand") was the only fairly regularly minted silver coin
issued by the late Roman and Byzantine Empires. It was struck with variable fineness, generally with a weight between 6.5 and 8.5 grams. The miliarense was struck from the beginning of the 4th century
under Constantine II
with a diameter of 22 mm , but it became more common from the 7th
to the 9th century
There were two kinds of miliarense: light and heavy. It took 14 heavy miliarensia and 18 light miliarensia to equal one solidus.
