The Spanish€1 and €2 coins bear the portrait of King Juan Carlos I, who reigned from 1975 until 19 June 2014. He earned great respect for his important role as a mediator following the death of Francisco Franco, in the difficult transitional period from dictatorship to democracy. This motif for the Spanish €1 and €2 coins was designed by Luis José Diaz.
Euro coins and banknotes were introduced on 1 January 2002 in twelve countries. Today, the euro area has grown to include 18 countries. Euro coins feature a common design on one side. Also, the national side (reverse) of every coin includes a ring of 12 stars from the European Union flag. Each country has its own design for the national side of its coins.
