The aim of the article is to draw attention to a sole find of a clay mold for casting counterfeit coins of Emperor Leopold I. The artifact was unexpectedly unearthed at the National Cultural Monument Pustý hrad (Deserted Castle) in Zvolen. In the 2019 research season, during the excavation of the rubble backfill of the flanking tower ditch in the eastern line of the Upper Castles fortification, five fragments from a casting mold were discovered. The item serves as proof of counterfeiting activity, and it is a unique modern find, dated at the end of the 17th Century, not only from Deserted Castle, but in general from the territory of Slovakia, as we do not know a similar artefact from other castles.
