In the Roman currency system, the denarius (plural: denarii) was a small silver coin first minted in 211 BC. It was the most common coin produced for circulation but was slowly debased until its replacement by the antoninianus.

The word denarius is derived from the Latin dēnī "containing ten", as its value was 10 asses.
