Najnowsze nabytki Gabinetu Numizmatyczno-Sfragistycznego Zakładu Narodowego im. Ossolińskich. Przyczynek do dyskusji na temat wrocławskich denarów z imieniem Bolesława

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.
