The 2005 Vatican City 2 euro standard issue coin features a unique design marking the Sede Vacante, the period when the Holy See is vacant following the death of a Pope. The national side displays the coat of arms of the Camerlengo, the official responsible for the administration of the Apostolic Camera during this interim, positioned above the crossed keys of Saint Peter and the umbraculum. Surrounding these central symbols is the inscription 'Sede Vacante' along with the year of issue and the name of the issuing state. This design reflects the solemn transition of power within the Vatican, a tradition central to the governance and history of the Catholic Church. The coin was issued as part of the 2005 annual set.
