The króna (plural: krónur) is the currency of the Faroe Islands. It is issued by the Danish National Bank. It is not an independent currency but a version of the Danish krone. Consequently, it does not have an ISO 4217 currency code. The ISO 4217 code for the Danish krone is DKK. The króna is subdivided into 100 oyrur (singular oyra).
From 14 October, 1940, new banknotes were printed "on behalf of the National Bank of Denmark". The value of these new banknotes was the same as those already in use. On 18 December, 1940, a Currency Central was established in order to monitor foreign trade and to secure the solvency of the Faroes. Currency Central was headed by a board of nine, the judge, who was chairman, one representative of Faroe Fish Export, one representative of the Faroese Merchants' Union, one representative of the bank Føroya Banki, one representative of the savings bank Føroya Sparikassi and four representatives of the Løgting.
On 18 December, 1940, the Faroese Króna was pegged to the British pound at a rate of 22.4 krónur = 1 pound. This rate was officially accepted by the British government in a treaty titled "Agreement between His Britannic Majesty's Government and the Administration of the Faroe Islands, for Regulating the Financial Relations between the United Kingdom and the Faroe Islands" which came into force on 27 March, 1941. At the same time, the Board of the Currency Central was reorganized to only three members, one representative of the British Government, one representative of the State (referring to the State of Denmark, meaning the County of Faroe), and one representative of the Løgting or the parliamentary National Board. In 1941, coins were struck in London for use on the Faroe Islands.
As of 12 April, 1949, the Faroese króna was separated from the pound sterling and fixed to the Danish krone at parity. This arrangement is still in effect. Although Faroese banknotes were issued "on behalf of the National Bank of Denmark", the National Bank of Denmark does not claim any rights to Faroese banknotes issued prior to 1951.
During the late 19th German national C.F. Siemsen, a merchant conducting business in both the Faroe Islands and Iceland, issued his own private coinage. This issue is brass, one side carrying the insciption: CFS and the other side the denomination: 4 or 16 skilling in goods ("x SKILLING I VARE"). Due to a shortage of currency in 1929-33, two merchants issued their own coins as well; J.F. Kjølbro in Klaksvík and S.P. Petersens Eftf in Fuglafjørður. The Kjølbro issue is aluminium coins with denominations of 10, 25 and 50 øre, and 1, 2, 5, and 10 kroner. S.P. Petersens Eftf's issue was made of brass in denominations of 5, 10 and 25 øre, and 1, 2 and 5 kroner.
During World War II, the Faroe Islands were separated from Denmark proper due to the occupations by the United Kingdom and Germany respectively. In 1941, a set of coins (1, 2, 5, 10 and 25 øre) was minted in London to alleviate a shortage of small change. This issue was identical to the pre-war Danish coinage already circulating, but is easily identified: the coins minted in London were made of bronze and copper-nickel, while the comparable coins minted in Denmark in 1941 were made of aluminium and zinc (with one exception). In addition, the British made set lacks both the mark of the Royal Danish Mint (a small heart) and the initials of the engraver and the mint master in Copenhagen.
