100 Dinara

Yugoslavia's 1963 constitutional reform — which redesignated the country the "Socialist Federal Republic" — triggered a wholesale reissue of currency bearing the updated state name. This note is part of that transitional series, replacing earlier Narodna Banka issues without any change to the monetary system itself; the redesign was political housekeeping, not economic necessity.

Engraving credits split between Krnjajić on the obverse and Kocmut on the reverse, a division of labor common at ZIN during this period and worth noting for variety collectors tracking die-specific wear patterns.
