Three coins were found during a small archaeological excavation at the medieval castle in the Lower Silesian village of Stare Kolnie (Popielów Commune, Opole County, Opolskie Voivodeship): a Silesian kwartnik from the beginning of the 14th century, a Wrocław heller from the years 1417-20 and a counterfeit Polish half-groschen struck after 1410. The kwartnik belongs to the oldest artifacts found at the castle, whereas the fifteenth-century coins were found in the layer related to the final demolition of the castle during the fighing in 1443.

Common counterfeits of small copper shillings of King John Casimir, originally coined between the years 1659 and 1666, were researched reluctantly. The 17'hcentury hoard from Idźki-Wykno (Wysokie Mazowieckie County, Podlaskie Voivodeship), uncovered in 1969 gave us a new opportunity to take up this issue, thanks to its large representation of counterfeits.

The subject of this study is a stater found in Masłów (Lower Silesia) in 1704: the oldest documented find of a Celtic coin from the area of the present-day Poland. The coin, which has been regarded as missing until recently, was successfully identified with a high degree oflikelihood in the collection of the Staatliche Museen in Berlin. The present study has carried out an analysis of the unit and the records concerning it, particularly emphasising the issues related to iconography, examined against a broad comparative background. The summary includes conclusions concerning the place of striking and dating of this unique coin.

In 2011 twelve early medieval coins found their way to the collection of the Coins, Medals and Seals Department of the Ossolineum, including nine cross pennies of the types VII (Crosier) and VIII (Hand-head), a penny of Boleslaus the Bold of the 'royal' type, and two specimens with the names of Boleslaus and St John, extremely rare and interesting, attributed to the Wrocław mint. Part of these: the two pennies with St John's name and cross pennies of type VII, may derive from a scattered hoard from the village of Kopacz, Złotoryja County, Dolnośląskie Voivodeship.

A drachm of Trajan struck in 98 AD in the mint in Lycia was uncovered at a settlement of the Przeworsk culture at Łęki Majątek (Kutno district). The coin was found in a pit house dated at the beginning of phase C2 of the Late Roman Period (c. 260--c. 280 AD). A good state of preservation of the coin indicates that most of the time it remained hidden in a hoard.
