Surface prospection at site 5 in Nieprowice, Pińczów county, Świętokrzyskie voivodship, revealed a quite large series of Roman coins (33 specimens), accompanied by numerous and differentiated artefacts of the Przeworsk culture. Many of the artefacts are metal decorations and elements of dress that usually provide precise dating of archaeological sites. Site 5 at Nieprowice was occupied by people of the Przeworsk culture beginning with phase A2 of the younger Pre-Roman Period to the beginning of the Migration Period. The coins are exceptionally abundant and they are more differentiated than it is usual in surface prospection on the sites of the Przeworsk culture settlements, hence this place could be a central settlement in the region.
In Sowinki near Poznan 150 graves were discovered during archaeological examination of an inhumation cemetery from the 10th–12th century. The following four coins were found in the graves: 1. a fragment of an Arabic dirham from the 10th century, 2. a fragment of King Otto III’s (983–996) pfennig of Trier; 3. a fragment of a coin imitating Otto- Adelheid pfennigs; 4. a whole cross penny from the 11th century. The round plate, lost before examination, may have been the fifth coin. In grave 76 a two-pan scale was found, together with 18 weights: 6 from bronze-coated iron and 12 from lead. All the finds were made in the older part of the site, dated to the end of the 10th and the first half of the 11th century.
