The Vatican and Italy signed an agreement in 2000, enabling the Holy See to adopt the euro as its official currency and to mint its euro coins from 2002. Vatican euros are legal tender now both in the Vatican City and Italy and they can be circulated freely throughout the entire eurozone. They resemble those of eurozone countries, and the "national" illustration on one side of the coin has seen various changes through the years but has featured a series of three effigies of Pope Francis since 2014.
