X-ray 2D imaging and 3D computed tomography are increasingly used for surveying archaeological finds and objects of cultural heritage. As examples of non-destructive methods, they can be used for the inspection of the inner structures of objects without modifying their original form. The contribution deals with the possibilities, limitations and results of a tomographic survey of a uniquely preserved hoard of coins discovered in 2020 near the village of Hradce in southern Bohemia (Czech Republic). The hoard was deposited in a ceramic vessel about 17 cm high and with a diameter of about 15 cm at the widest point. The weight of the hoard is 3.8 kg, and it contains more than 5000 coins dating back to the fourteenth and fifteenth centuries. A small number of coins are still wrapped in fabric since the fifteenth century. The contents of this fabric package in terms of the amount and type of present coins have been identified by X-ray tomography.
