Amongst the first imported silver coins from western Europe in hoards in the territories of the western Slavs after the decline of silver import from Central Asia are issues anonymous in both respect of ruler and mint which have been in discussion since the early nineteenth century. In research they have been called by various names such as Sachsenpfennige, Hochrandpfennige, Kreuzpfennige (German) or krzyżówki (Polish) and must originate from mint(s) in Eastern Saxony bordering Slavs. They are of importance for the understanding of the use and chronology of coined silver in Slavic lands, especially in Poland and eastern Germany. The example of the Strandby hoard in Denmark, where these occur in a larger number, are well documented and to a larger part are unfragmented, allows us to show that the hitherto used dating (Kilger 2000) is incorrect. All known varieties must have been struck before 983/984 and not up to c. 1000. There is no continuation to younger series with hammered edge appearing since early eleventh century.

During archaeological excavation conducted in 2017 between the streets of St. Katarzyna, St. Wit, Wit Stwosz and Nowy Targ Square in Wrocław 46 numismatic objects were discovered – 37 coins, 4 jetons, 4 objects related to numismatics (silver planchet, a small piece of cast silver and two containers for bracteates – one lid and one bottom, from various containers) and one lead token. Early medieval, late medieval and early modern coins appeared. The most interesting are the thirteenth-century Silesian bracteates of the Ratajski and Kałowice types. During excavation a rare Prague parvus of Wenceslas II was also found. Among all the coins, one of the most interesting is counterfeited West Pomeranian denier of Bogusław I, Duke of Pomerania. All analyzed coins constitute a cumulative find that was found in one of Wrocław’s auxiliary markets of medieval origin.
