Frederick IX portrait, looking right.

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

Crowned royal arms dividing date, value above, two oak twigs below.

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.
