I checked it using Numista and could not identify it! This is closest I could get
https://en.numista.com/catalogue/pieces63480.html
On its obverse we can see letter "S" just like on Wilno or Riga mint Szelag.
But its reverse is weird. First of all I can not identify the coat of arms. It resemble Wilno mint a bit but have different pictures.

This is Wilno mint coat of arms https://static-numista.com/catalogue/photos/pologne-lituanie/g428.jpg

But mine have standing man instead of Knight on horse or int right part. Also there is no date on left top part but two letters "SM" and some dot "*" so its more lime SM*
So I assume it's Polish Lithuanian Szelag coin of Sigismund III Vasa and coin was minted somewhere between 1587 to 1632. But I need to know its mintcity coat of arms and where its date. Why "SM*" ?
Hope you can help
