The paper money of the Hungarian korona was part of the circulating currency in the post-World War I Kingdom of Hungary until the introduction of the pengő in 1927. The variety of the banknotes and treasury notes and the variety of issuing authorities reflect the chaotic postwar situation in the country.
The Oesterreichisch-ungarische Bank / Osztrák-magyar Bank, the joint bank of the Monarchy had the exclusive patent to print banknotes throughout the Austro-Hungarian Empire. Banknotes were printed in Vienna, Hungary was supplied from there. During the First World War, the chief secretary of the Vienna headquarters intentionally suspended the delivery of banknotes to Hungary. After the World War, the Hungarian Károlyi government requested the joint bank to deliver printing plates and banknote paper to Hungary, since it would have been too dangerous to deliver printed banknotes due to the political uncertainty. The banknotes printed in Budapest under the Károlyi government and then under the Soviet Republic were distinguished with a different serial number. After the fall of the Soviet Republic, Vienna declared these banknotes to be counterfeits.
The Postal Savings Bank notes were issued under the decree of the Revolutionary Governing Council of the Hungarian Soviet Republic by the Magyar Postatakarékpénztár, which was acting as the emission bank of Hungary then. The prewar high denomination banknotes of the Austro-Hungarian Bank were deposited at par to prevent inflation.
Overstamped Austro-Hungarian Bank notes (1920)
Hungary was the last country among the successor states of the Monarchy to execute overstamping of the common money. The Károlyi government planned to start it on 21 March 1919, but the establishment of the Soviet Republic postponed these plans. Finally, the banknotes were overstamped from 18 March 1920. Hungary used a red, round stamp to mark the banknotes.
State notes (1920-1926)
were first issued in 1921. The designer was Ferenc Helbing. The banknotes were first printed in Switzerland by then in Hungary by the newly founded Banknote Printing Co. in Budapest. The banknote size was increasing with the higher denominations, which prompted the press to resize the banknotes: from 1923, smaller versions were printed with the same design. Main state note printing mark variations:
Low denomination bills : no mark
Large size bills : ORELL FÜSSLI ZÜRICH
Small size bills : ORELL FÜSSLI ZÜRICH or Magyar Pénzjegynyomda Rt. Budapest. or no mark
All large and small size bills : T. W. or W or T. WILLI to show the name of the inventor of the photo guilloche technique used to print the state notes
After 25 August 1926 the 1000 to korona banknotes were overstamped to show the value in pengő.
