From the annexation of the Polish territories in the thirteenth century, Neumark and Torzym Province (Land Sternberg) became districts of the Margraviate of Brandenburg. Neumark belonged temporarily (1402–1454) to the Teutonic Order. From the very beginning, the two regions clearly varied in their coin circulation. The earliest Brandenburgian denier fi nds from east of the Oder River date to the last decade of the thirteenth century. However, the most important differences in the coin circulation became noticeable only after the middle of the fourteenth century.

Two whole and four halved Brandenburg deniers were found near Międzyrzecz. They were probably a part of a hoard discovered earlier, perhaps at the turn of the 19th and 20th century. The circumstances of the discovery did not allow for obtaining metrological data, but the authenticity of the find should not raise any doubts. The coins of Margraviate origin (undoubtedly there are at least four of them: Nos 1–4), were indicatively minted in the 1275–1295 period. The last two deniers (Nos 5 and 6) are also undoubtedly Ascanian, although their Brandenburg origin is not certain (they may belong to the Anhalt or Saxon-Wittenberg issue). All identified Brandenburg deniers from the vicinity of Międzyrzecz have analogies in finds registered in Poland within present borders. This small hoard, according to the newest systematics, was hidden around the year 1300.

Eight coins (seven medieval and one modern) were found during archaeological rescue excavation on the Main Market Square in Kalisz in 2012. Four coins (including one fragment) are hohlpfennigs, probably all of them are of Polish origin (from Greater Poland?) and date from the thirteenth-fourteenth century. The next three are: a halved penny, perhaps from the end of the thirteenth century, West Pomeranian penny and, probably, a Silesian heller from the fourteenth-fifteenth century. The modern coin is a heavily worn copper shilling by John Casimir (1648–1668).

The suburb of Kalisz, called the Old Town, is a historical craft and trade settlement located near the ducal castle — the early medieval town of Kalisz. In 2001, during archaeological excavations a number of coins were discovered at this location. Six of them are the subject of this paper. They are bracteates struck in the second half of the 13th century, probably in Greater Poland during the reign of Przemysł II (†1296).
