1 Hào

The National Bank of Vietnam's 1958 hào notes were part of the Democratic Republic's effort to build a coherent currency system in the North following partition. The 1 Hào was among the smallest denominations in practical circulation, used for everyday transactions in an economy still largely driven by agricultural exchange.

The print date of 30 April 1945 in the catalog data almost certainly reflects a reference error or plate notation — the National Bank of Vietnam did not exist until 1951.
