The portrait of young Constantine II left, date below, inscription "Constantine King Of Greeks" around.

Constantine II (born 2 June 1940) reigned as the last King of Greece, from 1964 until the abolition of the monarchy of Greece in 1973. He acceded as king following the death of his father King Paul in March 1964. Although the accession of the young monarch was initially regarded auspiciously, his reign soon became controversial: Constantine's involvement in the Apostasia of July 1965 created unrest among sections of the population and aggravated the ongoing political instability that culminated in the Colonels' Coup of 21 April 1967.

The coup was successful, leaving Constantine, as the head of state, little room to maneuver since he had no loyal military forces on which to rely. As a result, he reluctantly agreed to inaugurate the Greek military junta on the condition that it be made up largely of civilian ministers. On 13 December 1967, Constantine was forced to flee the country, following an unsuccessful countercoup against the junta. He remained (formally) the head of state in exile until 1 June 1973, when the junta abolished the monarchy, permanently. This abolition was confirmed after the fall of the junta by the Greek republic referendum, 1974 on 8 December 1974, which established the Third Hellenic Republic. Constantine, who was not allowed to return to Greece to campaign, accepted the results of the plebiscite.

Depicts the emblem of the Junta: the Phoenix rising from its flames and the silhouette of the soldier bearing a rifle with fixed bayonet. On the header the word Kingdom of Greece and on the footer 21 April 1967, the date of the coup d'état, can be seen in Greek. Denomination below.
