Head of Frederick IX with titles right, mint mark and initials C-S below.

Mintmaster's initial: C (Alfred Frederik Christiansen, 1956-1971).

The heart (♥) is the Royal Danish Mint mark (h, Copenhagen). The use of the heart is a century-old tradition, originally indicating the mint master, later the place of minting. Today, the mint mark serves no practical purpose since Danish coins are minted in only one place.

Moneyer's initial: S (Harald Salomon, 1930-1968).

Head of Princess Margrethe (Queen after 1972) left, date of 18th birthday, value below.

Margrethe II (born 16 April 1940) is the Queen of Denmark. She is also the supreme authority of the Church of Denmark and Commander-in-Chief of the Danish Defence. Born into the House of Glücksburg, a royal house with origins in Northern Germany, she was the eldest child of Frederick IX of Denmark and Ingrid of Sweden. She succeeded her father upon his death on 14 January 1972, having had become heir presumptive to her father in 1953, when a constitutional amendment allowed women to inherit the throne. On her accession, Margrethe became the first female monarch of Denmark since Margaret I, ruler of the Scandinavian kingdoms in 1375–1412 during the Kalmar Union. In 1967, she married Henri de Laborde de Monpezat, with whom she has two sons: Crown Prince Frederik (born 1968) and Prince Joachim (born 1969). She has been on the Danish throne for 45 years, becoming the second-longest-reigning Danish monarch after her ancestor Christian IV.
