; code: DKK) is the official currency of Denmark, Greenland, and the Faroe Islands, introduced on 1 January 1875.

The krone is pegged to the euro via the ERM II, the European Union's exchange rate mechanism.

[5] The oldest known Danish coin is a penny (penning) struck AD 825–840,[6] but the earliest systematic minting produced the so-called korsmønter (lit.

[7] Organised minting in Denmark was introduced on a larger scale by Canute the Great in the 1020s.

Lund (now in Sweden) was the principal minting place and one of Denmark's most important cities in the Middle Ages, but coins were also minted in Roskilde, Slagelse, Odense, Aalborg, Århus, Viborg, Ribe, Ørbæk and Hedeby.

The metal content of minted coins was subject to debasement over the centuries, an easy way to generate income for the monarch and/or the state.

Danish currency was overhauled several times in attempts to restore public trust in the coins, and later issued in paper money.

In more general use until 1813, however, was a krone or schlecht daler worth 2⁄3 rigsdaler, 4 marks, or 64 skilling.

Denmark borders one eurozone member, Germany, and one other EU member, Sweden, which is legally obliged to join the euro in the future (though Sweden maintains that joining ERM II is voluntary, thus avoiding euro adoption for the time being).

Faroe Islands and Greenland have their own IBAN codes (FO and GL, while Denmark has DK).

The first series, 20-krone coins featuring towers in Denmark, ran between 2002 and 2007 and spawned ten different motifs.

The last coin depicting the Copenhagen City Hall was issued in June 2007, marking the end of the series.

In 2005, Danmarks Nationalbank issued the first in a series of five 10-krone commemorative coins with motifs from Hans Christian Andersen's fairy tales.

Featuring motifs of a polar bear, the Sirius Sledge Patrol and the Aurora Borealis, the coins aimed to accentuate scientific research in the backdrop of Greenlandic culture and geography.

Every note had a portrait based on a painting by Jens Juel on the obverse side.

[22] Illustrated by Johan Alkjær, the banknotes featured portraits of Danish artists and scientists on the obverse while the reverse had motifs of cultural and religious art.

Among the new security features is a window thread ("Motion") with a moving wave pattern.

Starting in 2020, Danmarks Nationalbank released a new version of the 500-kroner banknote with updated security features, the first in the 2009A series.
