Rare first vintage of Prussian groschen of Sigismund I the Old.
Variety with the ending of the obverse and reverse legend PRVSS and with a symbol starting the reverse legend in the form of a circle, with a dot in the middle, instead of a rosette.
Variety unlisted in the Corpus Nummorum Civitatis Thorunensis catalogue, where a variety with a similar symbol is listed under number 1194, but in the obverse legend.
Ex. Green Raven Collection.
Hints of mint luster.
