5 Dinara Silver

The X# prefix places this outside Yugoslavia's regular circulation coinage entirely — it was struck for the numismatic trade, almost certainly by a private mint, and never authorized as legal tender by the Narodna Banka Jugoslavije. These pattern-style or fantasy pieces were common in the 1970s and 80s, often produced to satisfy collector demand in Western markets for silver issues from socialist states that had long since abandoned silver in domestic circulation. Yugoslavia's official 5-dinar coin by 1982 was a copper-nickel piece of no particular distinction.
