Byzantine coinage began effectively with the reign (491–518) of Anastasius I. Henceforth, it consisted, in addition to gold, of silver and bronze. Silver, always rather rare, consisted of the small siliqua (1/24 of a solidus) or keration, followed by the larger miliaresion and the still larger hexagram.
