Bydgoszcz orth, the obverse of which is illustrated in the Shatalin-Grendel catalog (p.21,fig.1).
Rare variety with a denomination mark of 16 under the bust of the king.
Obverse legend ending in PRV MA, on the reverse labrys in the form of extended spirals, and in the crown four dots and three crosses.
A very nice piece, with luster and charming patina.
Definitely recommended!
