The unusual face value of one and a half scripula was equivalent to 3/8 of a solidus, or 9 siliques. Introduced by Constantine I at the same time as the semissis, which was a half-solidus, it was minted sporadically until the end of the fourth century, and all known types are very rare. The introduction of the tremissis, a more practical coin of a third of a solidus, equivalent to 8 silicas, by Theodosius I around 383, eventually led to the establishment of the three-part Roman coinage system: solidus, semissis and tremissis, which remained in force until the Byzantine period.
