On 26 January 2015, during ploughing, 23 silver coins and silver items (four pieces of molten silver, a small bar and a piece of a silver lamina) were found on the field in Grzymisław (gmina Debrzno, powiat człuchowski). The hoard was dated to the early eleventh century. It includes mainly coins of German origin — primarily from Saxon mints. Second group consists of one dirham and dirham fragments (3 items). Apart from them one Anglo-Saxon coin of Aethelred II was distinguished.
In 2016 near Bornity (Braniewo district) a so far unknown stronghold was discovered. Within a small area the researchers unearthed a quarter of an early ̔Abbāsid dirham, a bronze spur with bent-in hooked extremities and a fragment of a ring of the Perm-Glazow-Duesminde type. In 2017 a preliminary small test excavation was carried out at the site. The discovered items and radiocarbon analysis of the charcoals from the rampart structure indicate that the site was in use in the last decades of the 9th century and the first quarter of the 10th century. Among the discovered artefacts the Arabic dirhams (two Hārūn ar-Rašīd’s dirhams and one al-Mahdī’s coin) deserve special attention and are discussed in detail in the article.
