Half-grove type without a mark under the crown, dated 1408-1410.
Tri-leaf as punctuation mark of the legend.
Interesting letter A in the word WLADISLAI - more like an inverted N.
A mint piece, with beautiful luster.
Definitely recommended.
obverse: crown and all around legend MONE WLADISLAI
reverse: Jagiellonian eagle and all around legend REGIS POLONIE
