John II Casimir, 18 groschen 1664, Vilnius - NGC AU58

An exquisite, select, circular piece.
A coin with a lustrous background and a charming fine patina.
The highest, among those given so far, rating in the NGC grading.
Currently the only one so highly graded among the Lithuanian orts of John Casimir!
A great rarity in such a state of preservation.

A variety with borders on both sides of the coin and the legend (...) CASIMI (...) POLO (...) on the obverse.

This piece, without a doubt, can be an adornment of any, even the most exquisite collection.
Definitely recommended.
