5 Para

Yugoslavia's small-denomination coinage of the mid-1960s survived largely because the country's self-managed socialist economy, unique among Cold War states, generated enough internal commerce to keep fractional coins in genuine circulation. The 5 para sat at the very bottom of a decimal system introduced after the 1945 dinar reform, itself a tool for wiping out wartime occupation currencies and the wealth held in them.

Aluminium brass was a deliberate choice for low-value Yugoslav coinage of this period — cheaper than the cupro-nickel used on higher denominations, yet durable enough for pocket use in an industrializing economy.
