It is indeed the Vatican.

 

A bit more about it:

The Vatican is the only country in the world to have ATM’s that speak Latin. Latin is the official language of the Vatican and one can choose this option by simply pressing the button. Rumor has it, that the former Pope Benedict XVI, loved his transactions done in Latin.

 

The economy of Vatican City is supported financially by the sale of stamps, coins, medals, and tourist mementos as well as fees for admission to museums and publication sales. The Vatican City state employed 4,822 people in 2016.

 

The Vatican City issues its own coins and stamps. It has used the euro as its currency since 1 January 1999, owing to a special agreement with the European Union. Euro coins and notes were introduced on 1 January 2002—the Vatican does not issue euro banknotes. Issuance of euro-denominated coins is strictly limited by treaty, though somewhat more than usual is allowed in a year in which there is a change in the papacy. Because of their rarity, Vatican euro coins are highly sought by collectors.
