On 5 March 2016, a resident of Przezmark announced the discovery of a hoard of 86 Roman denarii dating to the first and second century. The coins were located on the surface. From October 27 to November 2, 2016, archaeological research was carried out at the site of discovery. Seven denarii and two fragments of hand–crafted pottery from the period of Roman influence were discovered during the investigations. On October 27–28, 2017, another archaeological survey took place, during which an additional seven denarii were discovered. In total, 100 coins were recovered, which are currently in the Museum in Ostróda. The results of the excavations and field prospecting enable the interpretation of the site as a domestic space or cemetery to be ruled out, and the coin hoard is best understood as being concealed for economic or religious purposes.
