Juan Carlos I (born 5 January 1938) reigned as King of Spain from 1975 until his abdication in 2014. Juan Carlos is the grandson of Alfonso XIII, the last king of Spain prior to the monarchy's abolition in 1931 and the subsequent declaration of the Second Spanish Republic. Following his victory in the Spanish Civil War in 1939, Generalísimo Francisco Franco, the Spanish dictator, took over the government of Spain and in 1947, Spain's status as a monarchy was affirmed and a law was passed allowing Franco to choose his successor. Franco died in November the following year and Juan Carlos became king on 22 November 1975, two days after Franco's death, the first reigning monarch since 1931. Expected to continue Franco's legacy, soon after his accession, Juan Carlos, however, introduced reforms to dismantle the Francoist regime and begin the Spanish transition to democracy. This led to the approval of the Spanish Constitution of 1978 in a referendum, which re-established a constitutional monarchy.


Portrait in left profile of Juan Carlos I surrounded by the inscription "Juan Carlos I King of Spain", date below.



Depicts the facial value and the coat of arms during the Spanish transition to democracy (1977–1981). The exact year of issuing is located in the stars on both sides of the word "UNA".

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.

On either side of the coat of arms are the Pillars of Hercules, the mythological name given to the Straits of Gibraltar. The banner round the pillars is the national motto of Spain "Plus Ultra" which means "further beyond" in Latin, referring to the Americas and the former Spanish territories. Over the pillars are two crowns, one an Imperial Crown and the other a Royal Crown. King Charles I of Spain was also the Holy Roman Emperor Charles V, hence the Imperial Crown.
