During two seasons of archaeological investigation, in 2014–2015, on plot 168 in Puck, a total number of 29 numismatic items were discovered: 28 single coins and one token. The chronology of discovered coins is quite wide: coins from the 14th to the 20th century were registered, among them five medieval coins. In analyzed collection the most interesting are coins of the Teutonic Order — firchens and bracteates; moreover we have Polish and Prussian coins and also Tyrolean and Bavarian coins.

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.

Thirteen coins were found in archaeological excavations in the area of the old chartered town in Skarszewy, conducted between 16 and 26 October 2015. The finds comprised four Mediaeval coins and nine from Modern Times. The oldest is a firchen of Grand Master Winric of Kniprode, the youngest is a shilling of Frederick I from 1707.

During the museum query, which took place on 7 April 2016 in the Museum of Archaeology in Wroclaw an unknown parcel of the Grodziec hoard (district of Złotoryja) was revealed. This hoard was found in 1967. Two years later, it was published as a complex containing 492 coins: Polish, Bohemian and German groschen and half-groschen as well as two Gdansk shillings. Tpq was established as 1501. A parcel containing 173 Prague groschen had been completely left out of that publication. It contains coins of Charles IV, Wenceslas IV and Vladislaus II. The hoard dating had to be indistinctly altered (tpq 1502) and the quantitative composition of individual denominations turned out to be completely different. In the appendix the coins from the first part of the hoard are described, which were omitted or incorrectly described by M. Haisig. Especially interesting is the very rare groschen of the county of Henneberg.

The architectural and archaeological research conducted in 1977 was aimed at determining the stages of the church’s spatial development, which was to be achieved through analysis of its architecture, cultural accumulations, historical sources etc. During the research, eighteen coins were discovered — three early medieval ones and fifteen late medieval. The finds from St Elisabeth Church can be dated back to the period between the second half of the 13th century and the second half of the 14th century. The condition of some of the coins prevented complete identification. The discovered coins included Czech parvus coins (four), Wrocław city hellers (three) and other small coins which were in circulation at the time in Silesia.

The hoard from Krzczonów (Opatowiec community, kazimierski district) was discovered in 2002 during construction works on a private property. The entire deposit consists of 5,264 coins – Polish, Bohemian, Silesian, Pomeranian and Hungarian. The article presents 137 coins from the Krzczonów hoard – 128 Prague groschen of Wenceslas IV and nine hellers of Henry I, Duke of Münsterberg-Oels from the Kłodzko county. This small fragment of this hoard shows its scientific value and research perspectives. The very interesting results of the study of only a few percent of the entire find – inter alia the identification of the posthumous Prague groschen of Wenceslas IV – give high hopes that after the entire deposit has been processed, we will do much more about the monetary circulation in the late 15th century between Krakow and Kielce area.

During architectural and archaeological studies conducted in 1983 and 1985 at the site of medieval Ołbin Abbey, located in the Wrocław quarter of Ołbin, eight coins were found; six of them were analysed. These are late medieval and modern coins. All coins were precisely identified and described. Studies of the elemental composition of coins were undertaken with a non-destructive method, using X-ray fluorescence spectrometry. The results of analyses showed that coins were made from an alloy of copper and silver with varied content of main elements.
