Can someone please coment this 3 gr. 1598,Sigismund III Vasa coin . It's weight is 2,32 gr.,20-21 mm .
I have searched for this type in the catalog but unfortunately I couldn't find a type matching this coin . The weight seems to be regular but the design is very different from any other type of coins, from this yare.
How can this be explained ?
Sorry, about the pictures these are the best I could provide.
