Portrait in left profile of Juan Carlos I. Inscription "Juan Carlos I King of Spain" around. Date "1980" below.

Juan Carlos I (born 5 January 1938) reigned as King of Spain from 1975 to 2014, when he abdicated in favour of his son, Felipe VI.

In 1969, Francisco Franco, the Spanish dictator chose Juan Carlos, grandson of King Alfonso XIII, to be the next head of state, bypassing his father Juan de Borbón and expecting him to continue Franco's own authoritarian regime. Juan Carlos became King on 22 November 1975, two days after Franco's death, the first reigning monarch since 1931.

The facial value, the inscription ESPAÑA '82 and the coat of arms during the Spanish transition to democracy (1977–1981). The exact year of issuing is located in the star.

The Spanish coat of arms is composed of six other arms: castle of Castile, lion of León, stripes of Aragon, chains of Navarre, pomegranate flower of Granada and fleur-de-lis of the House of Bourbon. The escutcheon represents the currently reigning dynasty Bourbon-Anjou.

Franco adopted in 1938 a variant of the Coat of Arms reinstating some elements originally used by the House of Trastámara such as Saint John's Eagle. The arms are crowned with an open royal crown, placed on an eagle displayed sable, surrounded with the pillars of Hercules, the yoke and the bundle of arrows of the Catholic Monarchs.
