This 100 Lire Vatican City stamp, issued in 1952, beautifully portrays Pope Pius VI (1775–1799) in an engraved medallion portrait, a leader remembered for his devotion to the Church during tumultuous times. Beneath his image appears “La Sagrestia” (The Sacristy) of St. Peter’s Basilica, highlighting the architectural grandeur of Vatican heritage. Designed by C. Mezzana and engraved by T. Cionini, this deep carmine and black issue exemplifies the refined craftsmanship of early Vatican philately. A prized piece for collectors interested in papal history and ecclesiastical architecture.
