The distinctive feature of money circulation in the area of Cyrenaica during the first decades of the Roman Empire is a considerable demand for small coins. This feature is common for the overwhelming majority of monetized urban areas in the declining years of the Republic and the early days of the Empire, and it was also one of the main reasons for the flourishing practice of cutting coins. A major increase in bronze coin finds cut into halves and quarters resulted from the excavations of the Polish archaeological mission in Ptolemais. At present, the group of cut bronze coins found in Ptolemais consists of 62 specimens, 57 of which come from Polish excavations conducted in the years 2002–2009, whereas fi ve, being surface finds from the site area, are in the collection of the local archaeological museum. This article was enhanced by a set of 21 coins from Cyrenaica, held in private collections.

Large-scale counterfeiting of base silver coins of the Polish-Lithuanian state in the seventeenth century, using the technology of minting machines which were modern in those times, makes it possible to attempt a relatively precise identification of counterfeiting workshops. The article is an attempt to inventory and determine the place of production of milled false shillings of Sigismund III (1587–1632) and John Casimir (1648–1668) preserved in collections.

Based on the small finds of Roman denarii dating back to the first-third centuries, coming from the area of Poland, registered in 2004–2011 and compared to the composition of coin hoards of the same nominal value from the same area, one can venture to specify the chronology of these denarii infl ow more precisely. Two main inflow waves of denarii from the first-second centuries to the lands of the present-day Poland can be dated to the period from the second half of Antoninus Pius’ reign (138–161) to the early days of Marcus Aurelius’ reign (161–180) and the first years of Septimius Severus’ reign (193–211). When denarii are concerned alone, those waves were preceded by smaller ones, most probably during Trajan’s reign (98–117) and at the turn of Hadrian’s (117–138) and Antoninus Pius’ reigns. Few denarii from the third century, mixed with a small number of older denarii to some extent, came probably in the first half of the third century.

The subject of this study is a critical monograph of the gold coin hoard from Gorzów near Cracow, which is of essential importance for the research on Celtic coinage in Poland. During 120 years since its part had been unearthed and published in the 1890s, the hoard has been discussed and analysed many times, but no monograph has been dedicated to it. Preliminary research of the archive material and museum collections has considerably expanded the source base. A coin unknown in the previous literature has been revealed and the origin of other two has been correctly identified. Dating of the find, its character and the circumstances of hiding have been revised to put forward the hypothesis about its connection with the great Cimbri migration to the south in the second half of the second century BC.
