The 100 Dinara 1991 banknote was issued by the National Bank of Croatia during the country’s early independence period, serving as transitional currency before the introduction of the kuna.
The obverse features Ružer Bošković (1711–1787), the celebrated Croatian scientist and philosopher, framed with intricate guilloché patterns.
The reverse depicts the Zagreb Cathedral, symbolizing Croatia’s religious and cultural heritage.
Printed on paper with a watermark and embedded colored fibers, the note offered basic security for circulation.
Dimensions: 132 × 66 mm.
