Rare Polish hohlpfennig with a representation of a crown topped with a cross in the form of a pole flanked by two balls.
Coin classified by Borys Paszkiewicz as a non-Teutonic (Polish) imitation of Teutonic bracteats of the Crown I type, Paszkiewicz T6, which are dated to the years ca. 1287/1288-1297/1298. The imitation may have a similar chronology or the coins are a bit younger.
