A very rare type of trojak.
On the obverse a bust of the king with a fan-shaped orifice.
On the reverse, the date separated by the head of an ox (mark of mincmaster Szymon Lidman) and the Chalecki coat of arms (mark of treasurer Demetrius Chalecki).
Beautifully minted and preserved piece, luster and charming old patina.
Definitely recommended.
