Very rare Silesian parvus, not recorded in the literature, to which we know of no analogy among the kwartniks. The Silesian parvus were probably struck with the kwartnik stamps on smaller discs and are very rare. The image on the reverse is very similar to the reverse of the Friedensburg 430 coin. There is a continuous border on the reverse, not seen in the kwartnik coinage.
