The tremissis or tremis was a small solid gold coin of Late Antiquity.
Its name, meaning "a third of a unit", formed by analogy with semissis (half of a unit), indicated its value relative to the solidus.
It was introduced into Roman currency in the 380s by the Emperor Theodosius I and initially weighed 8 siliquae (equivalent to 1.52 grams).
