DO COINS BY ZBIGNIEW, WLADYSLAW HERMAN'S SON, EXIST?
Zbigniew, Wladyslaw I Herman's (approx. 1080-1102) elder son, is one of the few ruling Piast princes whose coins have not been identified as yet. In the years 1097-1106 the prince had authority in Great Poland, in the land of Sieradz and Leczyca, not later than from 1102 - also in Mazovia. Thus a question arises: didn't he ever start any coinage? As it is, he never produced any money with his name or image on it, yet, he seemed to have struck anepigraphic denarii with the image of a cross, called cross denarii. Two hoards from south-eastern Great Poland: from Kalisz and nearby Sluszkow, remarkably diversified in volume provide arguments for the foregoing assumption. They have been dated to the first years of the 12th century, i.e. Zbigniew's reign in Great Poland. The first of the hoards (recently discovered in the Old Town in Kalisz) comprises merely of 4 cross denarii of the youngest types, among them two specimens of the CNP 867-868 Type. Save for the hoard in question, coins of that kind are known only from the large cross denarii complex of Sluszkow, dated by a denarius of Hungarian Koloman (1095-1114) to approx. 1105. Among the preserved 13 061 coins, 12 829 are cross denarii - 1470 of them are specimens of the CNP 867-868 Type. The latter having been included in Zbigniew's coinage on the basis of the very late chronology thereof, corresponding to the prince's rule in Great Poland. Coins of another variant, older by a few years, similar to the CNP 813, may be also associated with the prince. Beyond south-eastern Great Poland (Sluszkow and Kalisz?), finds of the CNP 813 Type occurred in Sieradz and Leczyca land (CNP 813/858 denarius) and in Silesia (Krosno Odrzanskie? CNP 813/858). The large bulk of the preserved denarii appeared in the Sluszkow hoard -1916 complete specimens, the other deposits comprised just single specimens. Finds of the CNP 813 coins occurred in the territory ruled by Zbigniew at the turn of the 11th century; they might have made up his first issue of metal money. Obviously there is no unquestionable proof of the existence of Zbigniew's coinage, however he might have produced coins in the territory of his state in the last years of the 11th and at the beginning of the 12th centuries?
