Swedish coinage of King Sigismund III, with his monogram S-R (Sigismundus Rex) punctuated by Snopek and the full title of King of Sweden and Poland.
As Tadeusz Kalkowski emphasized,"the reign of King Sigismund in Sweden was quite short, the issues of his coins were not large, so they are quite rare there. All themore so in Poland they can be found only exceptionally, and only in larger collections."
