Vatican City "Conciliation" Definitive Series

Vatican City · 1929 · 5 Centesimi to 10 Lire

This series, known as the "Conciliation" issue, was the first set of postage stamps released by the newly independent Vatican City State. The designs feature the papal coat of arms of Pope Pius XI, including the papal tiara and the Keys of Saint Peter. The set consists of 13 definitive stamps and two special delivery stamps, marking the establishment of the Vatican's independent postal service.

Issued following the signing of the Lateran Treaty in 1929, which established Vatican City as a sovereign state, these stamps symbolize the newfound independence and political status of the Holy See.
