The Philatelic and Numismatic Office of the Vatican City State (Italian: Ufficio Filatelico e Numismatico) is responsible for issuing Vatican postal stamps and Vatican coins.
While Vatican stamps may only be used within the Vatican City State and the quantity of euro coins is limited by treaty with Italy (the total value of all coins minted in 2002 was restricted to €310,400), Vatican coins and stamps serve as an important sign of Vatican sovereignty, and their scarcity and design makes them popular with collectors.
Indeed, public interest in Vatican currency and stamps was considered sufficient to justify a Philatelic and Numismatic Museum (Il Museo Filatelico e Numismatico) which has been opened as part of the Vatican Museums in 2007. Two special stamps about the museum were issued at the museum opening.
Euro coins issued by the Vatican are minted by Italy's Istituto Poligrafico e Zecca dello Stato (Italian State Mint).
