Conjoined heads of King Frederick IX and Queen Ingrid right, date, mint mark and initials N-S below.

Frederick IX (1899–1972) was King of Denmark from 1947 to 1972. Born into the House of Glücksburg, Frederick was the eldest son of King Christian X and Queen Alexandrine of Denmark. During Nazi Germany's occupation of Denmark, Frederick acted as regent on behalf of his father from 1942 until 1943. Frederick became king on his father's death in early 1947. During Frederick IX's reign, Danish society shook off the restrictions of an agrarian society, developed a welfare state and, as a consequence of the booming economy of the 1960s, women entered the labour market. Denmark modernized, bringing new demands on the monarchy and Frederick's role as a constitutional monarch.

Ingrid of Sweden (1910–2000) was Queen of Denmark from 1947 until 1972 as the wife of King Frederick IX. Born into the House of Bernadotte, she was the daughter of King Gustaf VI Adolf of Sweden and his first wife Princess Margaret of Connaught. In 1935 she married Crown Prince Frederick of Denmark and they had three daughters, Margrethe, the present Queen of Denmark, Benedikte, now a Princess of Sayn-Wittgenstein-Berleburg, and Anne-Marie, the former Greek Queen. As queen, Ingrid reformed the traditions of Danish court life, abolished many old-fashioned customs at court and created a more relaxed atmosphere at official receptions.

Mintmaster's initial: N (Niels Peter Nielsen, 1927-1955).

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).

Map of Greenland below grid, country name in the Greenlandic language ('Land of the Greenlanders'), denomination below.

Greenland is an autonomous constituent country within the Kingdom of Denmark between the Arctic and Atlantic Oceans, east of the Canadian Arctic Archipelago. The majority of its residents are Inuit, whose ancestors began migrating from the Canadian mainland in the 13th century, gradually settling across the island. Greenland is the world's largest island. Three-quarters of Greenland is covered by the only permanent ice sheet outside Antarctica.

Greenlandic is an Eskimo–Aleut language spoken by about 57,000 Greenlandic Inuit in Greenland. It is closely related to the Inuit languages in Canada such as Inuktitut.
