An extremely rare coin, with almost the highest rarity grade of R8 given by Kopicki, who cites only the only piece known from the Hutten-Czapski collection, Tyszkiewicz valued at 150 marks in gold - not much less than the extremely rare Sigismund III thalers from STR valued at 200 mk. On the obverse centrally a large sheaf of Vasa, above it the numeral III, in the rim SIG III D G R POL M D L. On the reverse, under the crown a shield with an eagle and a chase, and below a shield with a levron on the sides; at the top a split date 15-91, at the bottom a monogram I-F. A TREMENDOUS RARITY FOR THE MOST DISTINGUISHED COLLECTIONS.
