The department represents the “point of contact” for all regional history numismatic matters. In addition to maintaining the museum’s collections, it is responsible for the scientific recording of the ongoing accrual of coin finds and advising and supporting other State museum institutions on numismatics.
Both the coin and medallion collection as well as the sigillographic (the study of seals) collection has been of central interest since the museum was founded. After blossoming in the 19th century the collection receded somewhat into the background in the first half of the 20th century. In the year 1943 it was requisitioned for the planned Führermuseum and not returned until 1945.
Since the 1970s, continuous targeted additions have been made to the inventory of the "Obderennsia" collection, according to the means available. After WWII, the sigillographic collection was largely handed over to the OÖ. Landesarchiv [Upper Austrian State Archive] and returned to the Oberösterreichisches Landesmuseum in 2013. The Kastner coin collection (Greek and Roman coins) and Eiselmayr endowment (Austrian coin scales and weights) represent the latest important endowments.
The numismatic portfolio currently includes around 60,000, approx. 8,000 objects of which are in the sigillographic collection. The numismatic collection contains above all coins and currency, medallions and their derivatives, as well as objects relating to the history of money and finance. The general collection contains objects from ancient Greece to the present, including an extensive inventory of Roman coins.
The “Obderennsia” collection includes all of the numismatic objects manufactured in and for Upper Austria. These also include all of the coins found on the territory of today’s Federal State of Upper Austria from the Celtic era to Modernity.
A cross section through the collection portfolio is on display in the Schlossmuseum Linz’s permanent exhibition (“Münzkabinett”).
Research focuses are on one hand the continuation of the catalogue raisonné "Numismata Obderennsia", which aims to collect all of Upper Austria’s numismatic objects, while the registration of and publication on the coins found is also a main source for the history of the historic currency. The development of a scientific inventory catalogue, also for Upper Austria’s other museums, represents an additional area of responsibility.
