The 1 Dinar 1991 banknote was issued by the National Bank of Croatia during the transitional period following the country’s declaration of independence from Yugoslavia. This series was quickly introduced to replace the Yugoslav dinar and served as emergency money until the introduction of the kuna.
The obverse features the portrait of Ružer Bošković (1711–1787), a renowned Croatian polymath, scientist, and philosopher. The background includes intricate guilloche patterns for anti-counterfeiting.
The reverse depicts the Zagreb Cathedral, one of the most important cultural and religious landmarks in Croatia.
The banknote was printed on paper, with basic security features including a watermark and security fibers.
Dimensions: 126 × 63 mm.
