Depicts the overlapping portraits of Kings Felipe VI and Juan Carlos I. At the bottom the name of the issuing country and the year of issuance. At the right, the mint mark (crowned M). The outer ring contains the twelve stars of the European Union.

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.

A geographical map of Western Europe spans the outer ring and inner core on the right side of the coin. The inscription 2 EURO is superimposed over the map of Europe, with the numeral “2” located in an open field representing the eastern Atlantic Ocean.

12 stars are located on the right side of the outer ring, with six stars atop the map of Europe and six stars below it; six vertical stripes cut across the inner core of the coin, visually connecting the upper and lower star segments.

Luc Luycx, a designer at the Royal Belgian Mint, designed the Euro’s common reverse; his initials, LL, are seen on the right side of the design, just under the “O” in “EURO.”

The sequence "2 ★ ★" repeated six times alternately upright and inverted
