In 1747, the Augustinian monastery of St. Florian in Upper Austria acquired the coin collection of the Venetian scholar and court poet at the Imperial court in Vienna, Apostolo Zeno necessitating the ordering and cataloguing of this collection of about 12,000 coins. Over the years, several canons regular were appointed as custodians of the collection. In addition, numismatists from the environment of the Imperial coin cabinet were repeatedly involved with the collection: Erasmus Frölich, Joseph Khell of Khellburg and the later directors of the Imperial coin cabinet Franz Neumann, Joseph von Arneth and Friedrich von Kenner.
Between 1760 and 1775 Georg Pfisterer was in charge of the collection of St. Florian. His correspondence with Joseph Khell includes more than 50 surviving letters. The presentation will focus on these documents and the numismatic questions discussed by the two correspondents.
