A COLLECTION OF POLISH MEDIEVAL AND POLISH-RELATED COINS. According to unpublished research by W. Nakielski, a denarius of Wladyslaw Herman - a copycat issue of Saxon cross denarii from the Wroclaw mint from the end of the 11th century, CNP type VIII, no. 1007-1013. Head of St. John with invaded long hair in the rim, on the reverse a straight cross alternating spheres and the letter V with a dot inside. The differences in the images of denarii with the head may also be due to the fact that they may also have been issued by Herman's son Boleslaw the Wrymouth.
