The Serbian dinar is the official currency of Serbia. The international official currency symbol; din / дин. The first signs of the Serbian dinar date from the reign of Stefan Nemanjić in 1214. During medieval Serbia, many Serbian rulers minted silver coins in dinars since this material was one of the primary sources of imports of the time since the Serbian mines had a relative abundance of silver. In 2003, the Serbian dinar replaced the Yugoslav dinar when the Federal Republic of Yugoslavia was transformed into the State Union of Serbia and Montenegro. The same year, the National Bank of Serbia introduced notes in denominations of 100, 1000, and 5000 dinars, followed by 500 dinars in 2004, 50 dinars in 2005, 10 and 20 dinars in 2006, and 2,000 dinars in 2011.
The 20 Serbian dinara note front design features the portrait of Petar II Petrović-Njegoš (1813 – 1851), who commonly known as Njegoš, was a poet, philosopher, and Prince-Bishop (Vladika) of Montenegro, on a background that presents a view of the Cetinje Monastery, located in Montenegro. The reverse of the note shows Petar II Petrović-Njegoš on a background that illustrates details of the first Slavic Octoechos (1494) and the Komovi mountain range. The design is completed with the National Coat of Arms. The lettering of the note is presented in the Serbian language. This note is part of the 2011 – 2013 series, and its color is green on a multicolor underprint.
