Rare, penultimate vintage half-penny of Sigismund the Old.
Variety with the error MONEA instead of MONETA.
Obverse: in the pearl rim an eagle, in the outer rim a legend:
+MAGNI:DVCIS:LITVANIE;
Reverse: in the pearl rim Pogon left, in the outer rim legend:
+MONEA:SIGISMVNDI:1528;
A very rare coin, especially in such exquisite condition.
