King Felipe VI of Spain and his wife Queen Letizia have featured on a coin unveiled by the Royal Mint of Spain Monday. The portraits of the royal couple appear on one side of the coin, while the other side features Don Quixote, a character in the Spanish classic by Cervantes. This is the first time that the couple have appeared on legal tender together, since Felipe was crowned king in June 2014.

The coin is of silver and valued at 30 euros. The coin commemorates the 400th anniversary of Don Quixote, whose second volume was published in 1615. The coin also has been made in a limited-edition version which would cost more as it is made of solid sterling silver.

One million coins have been produced by the Royal Mint of Spain. Felipe and Letizia feature on one side of the coin with their names and the year 2015 printed on one face of the coin. The reverse side has Don Quixote riding his trusted mare Rocinante while his sidekick Sancho Panza kneels beside them.

The picture of a windmill is seen in the inset, on the side where Don Quixote is pictured. There are lots of windmills described in the novel which is typically found in the Castilla-La Mancha region.  

The 47-year-old king ascended to the throne after the abdication of his father King Juan Carlos, who was 77. He stepped down on June 18 and the coronation of his son took place the very next day.

Meanwhile, the family-of-four were seen together to celebrate the national day of Spain in October. Felipe and Letizia were there along with their daughters Princess Leonor and Princess Sofia, who are ten and eight respectively. The family watched a military parade marking the special day in Madrid.

They also took their place in a balcony as aircraft from the Spanish military performed a fly-past. The celebrations were in honor of the country’s national holiday, which commemorates both the arrival of Christopher Columbus in the new world and Spain’s armed forces day. They watched a fly-past as the aircrafts left trails of red and yellow smoke, while over 3,400 troops marched through the centre of the city.
