Bohemia, John I, Prague groschen

A very nice Prague penny. Lots of luster.

It is worth remembering that John I of Luxembourg was the titular king of Poland, until 1335.

Obverse: in the inner rim a crown, in the outer rim a legend:
+IOhANNES:PRIMVS/+DEI GRATIA+REX:BOEMIE;

Reverse: in the rim a Bohemian lion, in the outer rim legend:
*+*GROSSI:PRAGENSES;
