20 Stotinov

Slovenia's tolar coinage was introduced in 1992 as the newly independent republic replaced the Yugoslav dinar, itself already collapsing under hyperinflation. The aluminium-magnesium alloy chosen for this denomination was a pragmatic response to the country's limited currency reserves in its first years of sovereign monetary operation — lightweight and cheap to produce, though notoriously prone to corrosion in circulation, which explains the high frequency of worn or discolored survivors despite the relatively short series run ending before euro adoption in 2007.
