50 Dinara SFR legend

Yugoslavia's 1963 coinage series marked the country's constitutional overhaul that same year, when the Federal People's Republic was formally renamed the Socialist Federal Republic — hence the SFR designation that distinguishes this type from its immediate predecessors. The change was more than cosmetic; the 1963 constitution was Tito's most ambitious attempt to codify self-management socialism as a governing principle, decentralizing economic authority to workers' councils in a deliberate break from Soviet-style central planning.

The KM#41 is distinguished from the otherwise similar KM#38 specifically by that updated state title on the obverse legend.
