An important decision for the establishment of the monetary system of Serbia followed in 1873 during the reign of the Prince, and then King Milan Obrenović (1868-1889) with the enactment of the "Law on the minting of the Serbian silver coin". The first silver coin was minted in 1875, when the national monetary unit, the dinar, was introduced following the example of Serbian medieval money. The very name 'dinar', which has remained as the monetary unit of the modern monetary system of Serbia, has a long history dating back to ancient Rome. Derived from the name 'denarius', as the Roman silver coin was called, it has remained present to this day in the names of national coins and other countries as is the case with Serbia, in whose medieval monetary history it represented a monetary unit.
