Very rare variety with the name of King Casimir in the legend of the obverse and reverse, with an interesting error in the legend of the reverse MONETΛ KΛZIMIRD and the Eagle without a shield on the reverse. Margine legends begin with star.
Kubiak type I.2, obverse legend no. 52, reverse legend no. 11 (among misspelled legends)
Exactly such a variety is listed in the Corpvs Nvmmorvm Civitatis Thorvnensis catalogue, where the authors misread the end of the reverse legend as KΛZIMIRV.
Obverse: double cross on the shield
KΛSIMIR D G R POLON
Reverse: Royal Prussian Eagle with a crown on and an armed arm on the right side
MONETΛ KΛ...RD
