The denarius (Latin pronunciation: [deːˈnaːrɪ.ʊs], pl. dēnāriī [deːˈnaːrɪ.iː]) was the standard Roman silver coin from its introduction in the Second Punic War c. 211 BC to the reign of Gordian III (AD 238–244), when it was gradually replaced by the Antoninianus. It continued to be minted in very small quantities, likely for ceremonial purposes, until and through the tetrarchy (293–313).:87
The word dēnārius is derived from the Latin dēnī "containing ten", as its value was originally of 10 assēs. The word for "money" descends from it in Italian (denaro), Slovene (denar), Portuguese (dinheiro), and Spanish (dinero). Its name also survives in the dinar currency.
Its symbol is represented in Unicode as 𐆖 (U+10196), however it can also be represented as X̶ (capital letter X with combining long stroke overlay).
