Frederick IX (Christian Frederik Franz Michael Carl Valdemar Georg; 11 March 1899 – 14 January 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. In 1935, he was married to Princess Ingrid of Sweden and they had three daughters, Margrethe, Benedikte and Anne-Marie. 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. Frederick IX died in 1972, and was succeeded by his elder daughter, Margrethe.

Mintmaster's initial: C (Alfred Frederik Christiansen, 1956-1971) or S (Vagn Sorensen, 1971-1978).

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).



Crowned royal arms dividing date, value above.

The national coat of arms of Denmark consists of three pale blue lions passant wearing crowns, accompanied by nine red lilypads (normally represented as hearts), all in a golden shield. It is historically the coat of arms of the House of Estridsen, the dynasty which provided the Kings of Denmark between 1047 and 1412. The current design was introduced in 1819, under Frederick VI. Previously, there had been no distinction between the "national" and the "royal" coat of arms. Since 1819, there has been a more complex royal coat of arms of Denmark (kongevåben) separate from the national coat of arms (rigsvåben).

The crown on the shield is a heraldic construction based on the crown of King Christian V. The sovereign's crown is the most important Royal and State symbol and represents national sovereignty. Since 1671 the crown of Christian V, which is kept at Rosenborg Palace, has been the Royal Danish crown. Made by Paul Kurtz in Copenhagen, 1670–1671. Gold with enamel and table-cut stones. Total weight 2080 g. Also 2 garnets and 2 sapphires, of which the largest dates back to Frederick I of Denmark.
