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. Exchange with the Danish krone 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 all 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. Also, exchange offices in other countries often have problems with them. People travelling from the Faroes are often advised to exchange their cash prior to embarking in order to prevent potential complications arising from this situation. Coins 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 (). 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
