100 Leva St. Petka of Bulgaria

St. Petka Tarnovska — also known as Paraskeva of Tarnovo — was a 14th-century Bulgarian ascetic whose relics became extraordinary political currency across the Orthodox world. Her remains were transferred from Tarnovo to Vidin, then to Serbia, and ultimately to Istanbul following the Ottoman conquest, where they remained for centuries before being moved again to Iași. That a Bulgarian state coin commemorates her is itself a quiet assertion of national continuity against a history of displacement and foreign rule.
