The currency of Denmark is called the Danish krone (abbreviated as DKK). It has been the official currency of Denmark since 1875, when it replaced the previous currency, the rigsdaler. The krone is also used as the official currency of Greenland and the Faroe Islands, which are both part of the Kingdom of Denmark.

The Danish krone is subdivided into 100 øre (singular: øre), although due to inflation, øre coins are no longer in circulation. The coins that are currently in use are the 50 øre, 1 krone, 2 kroner, 5 kroner, 10 kroner, and 20 kroner coins. The banknotes in circulation are the 50, 100, 200, 500, and 1000 kroner notes.

The value of the Danish krone is largely determined by market forces, and it is not pegged to any other currency or commodity. As with many other currencies, the exchange rate of the Danish krone can fluctuate widely depending on a variety of economic and political factors.

The Danish National Bank is the central bank of Denmark, and it is responsible for managing the supply of money and setting monetary policy. The bank seeks to maintain price stability and support the stability of the Danish financial system.

Denmark is a member of the European Union (EU), but it has chosen to opt out of using the euro as its official currency. While Denmark is required to join the euro under the terms of its EU membership, it has negotiated an exemption that allows it to maintain its own currency until it chooses to join the eurozone.

Overall, the Danish krone is an important part of the Danish economy and plays a key role in the country's financial system. While it is not widely used outside of Denmark, it is a stable and respected currency that is trusted by businesses and investors both within the country and around the world.
