A rare, early type of Cossack halberd.
Dated 1417-1430 (reign of Henry IX the Elder and Henry X the Younger Rumpold), much rarer than issues after 1440.
Distinguished from them stylistically: atypically shaped letter M (smaller, more tightly wrapped), the tower is also different (two windows on the central element, three blanks on the pointed tower).
Silver, diameter 10.5 mm, weight 0.12 g.
