In the Coin Collection of Johannes Gutenberg-University, there are collections of two institutions: The department of Ancient History and the Bischöfliches Dom- und Diözesanmuseum Mainz (episcopal museum). It consists of more than 1,000 coins, covering nearly the entire spectrum of ancient numismatics, from Archaic Greek to Late Antiquity and a few examples from the Byzantine period. The particular focus of the Mainz Coin Collection is on the 2nd to 4th century AD. All the coins are also in use for university teaching.
