Austria stamped the notes circulating in its territory with "DEUTSCHÖSTERREICH". The Austrian economy did not stabilise after the war, and a period of hyperinflation followed: the money supply increased from 12 to 30 billion Kronen in 1920, and to about 147 billion Kronen at the end of 1921. In August 1922 consumer prices were 14,000 times greater than before the start of the war eight years earlier. The highest-denomination banknote issued was the 500,000 Kronen note, issued in 1922. Faith in the currency had been lost, and people spent money as fast as they received it. In October 1922 Austria secured a loan of 650 million gold Kronen from the League of Nations, with a League of Nations Commissioner supervising the country's finances. This stabilized the currency at a rate of 14,400 paper Kronen to 1 gold Krone. On 2 January 1923 the Austrian National Bank (Österreichische Nationalbank) began operations, taking over control of the currency from the Austro-Hungarian Bank which had gone into liquidation. In December 1923 the Austrian Parliament authorised the government to issue silver 5,000, 10,000, and 20,000-kronen coins which were to be designated half-Schilling, Schilling, and double Schilling. The Schilling became the official currency of Austria currency on 20 December 1924, at a rate of 10,000 Kronen to 1 Schilling. Over-stamped Austro-Hungarian krone Croatia, Slovenia and Bosnia and Herzegovina In these territories of Austria-Hungary, which became part of the Kingdom of the Serbs, Croats and Slovenes (later Yugoslavia) in 1918, Krone banknotes were stamped by the new authorities and became issues of the Serb, Croat and Slovene krone. In 1920 this was replaced by the dinar at a rate of 1 dinar = 4 Kronen. Czechoslovakia In Czechoslovakia the currency was superseded by the koruna, at par. The names of the present-day koruna and haléř (in the Czech Republic) and the pre-Euro koruna and halier (in Slovakia) are derived from the Austro-Hungarian Krone and Heller. Fiume The Fiume Krone (Corona Fiumana) - (Cor., FiuK) was introduced on 18 April 1919 by over-printing the existing Austro-Hungarian Krone notes, under the authority of the Italian National Council of Fiume who ruled the city. There were two issues: the 1919/21 Issue (1 and 2 kronen), and the 1920 Issue (2, 10, 20, 50, 100, and 1,000 kronen). The over-printed notes were in circulation from April 1919 to February 1921. In September 1920 the Italian Lira was introduced as the
