An anonymous penny, a knight fighting a dragon upon one of its sides, Samson killing a lion on the other, has been found in a settlement in Kaldus near Chelmno. Similar coins have been known from Mianów near Lódz, albeit worse in the making and simplified, therefore what they present has remained unknown so far. As it is, the hoard from Ujma Duza near Wloclawek (Kuiavia) provided very similar coins, their types are different, though. Both the hoards so far have been dated after 1201, since the latest specified coins in them bore the name of Henry, the first Polish duke named so having started his reign in Wroclaw in 1201. This, however, does not whatsoever mean that the hoards could not contain later coins which we have not been able to specify so far. The author suggests that three further coin types from that hoard, those that are stylistic analogies to the coin from Kaldus, should be attributed to the next Kuiavian ruler, Duke Conrad I of Mazovia. The very coin of Kaldus, however, would be a next issue by the same duke, Conrad. The coins from Mianów which also present a dragonslayer and Samson, yet much worse in the making than the Kaldus coin might have been struck by Conrad, after he had captured Leczyca and moved his seat to it in 1230.
