The króna (plural: krónur; sign: kr) 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 and instead shares that of the Danish krone, DKK. The króna is subdivided into 100 oyru(r).
When German forces invaded and occupied Denmark on 9 April 1940, the Danish krone was used in the Faroes. However, all exchange between the Faroes and Denmark halted as a result of the occupation, leaving one currency to develop in two markets independently of each other. On 31 May 1940, special Faroese banknotes were introduced. They consisted of Danish notes with a special stamp. These notes replaced unstamped Danish at par.
On 18 December 1940, the Faroese króna was pegged to the British pound at a rate of 22.4 krónur = 1 pound. 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.
Danish kroner are exchanged to Faroese krónur and vice versa by the National Bank of Denmark free of charge. While normal Danish bank notes are no longer intended as legal tender in the Faroes, they are accepted there in most situations. In Denmark proper, existence of the Faroese króna is poorly known, particularly the fact that it is officially the same currency as the Danish krone and that the notes can be exchanged by any Danish bank without charge. Consequently, very few Danish stores will accept Faroese notes. People travelling from the Faroes to Denmark are often advised to exchange their cash prior to embarking in order to prevent potential complications arising from this situation.
The Faroe Islands use standard Danish coinage, but the region has experienced a shortage of small currency on several occasions, leading to non-standard issues.
During the late 19th century, 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 inscription: 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.
In 1940, Danish 5, 20, 50, 100 and 500 kroner notes were overstamped with Kun Gyldig paa Færøerne, Færø Amt, Juni 1940 (meaning “Only valid on the Faroe Islands, Faroe County, June 1940”) for issue on the Faroe Islands. Later that year, the Færø Amt issued distinct notes in denominations of 1, 5, 10 and 100 kroner. From 1951, notes were issued with texts in Faroese. The 1 kroner note was not continued, with 50 krónur introduced in 1967, followed by 500 and 1000 krónur in 1978, 20 krónur in 1986 and 200 krónur in 2003. Between 2001 and 2005, a new banknote series with new security features was introduced to replace older notes. Denominations are 50, 100, 200, 500 and 1000 krónur. On March 19, 2012 an updated version of the Faroese króna banknotes was released into circulation. The new notes are identical to the current issues, but the new notes now feature "Motion" windowed security threads and perfect registration devices instead of holographic patches on the fronts, and mother-of-pearl threads and fluorescent colors added on the back of the notes.
Faroese banknotes may be purchased by collectors at face value from Danmarks Nationalbank. Postverk Føroya, the Faroese postal service now known as 'Posta', used to be the sole supplier of Faroese banknotes to collectors, but does not sell banknotes anymore.
