A miliarense (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 3.8 and 6.0 grams. The miliarense was struck from the beginning of the 4th century under Constantine I with a diameter of 23 mm. The name was also applied to Byzantine silver coins from the 7th to the 11th centuries (see Miliaresion).
