A much rarer variety of variation.
Distinguished by an additional beam under the royal crown.
Illustrated in Sebastian Pawlikowski's specialized catalog with only one piece out of 65 type 13 varieties (but not distinguished in the text section).
According to the owner's oral account, coming from Kalkowski's collection (without his envelope).
Very nice obverse. Drawer patina.
Type dated 1408-1410, characterized by lack of additional mint marks, straight crown and Classical A letters (instead of Gothic).
