One of the rarest varieties of Ruthenian regiments - the first, Polish copper coins.
A variety without the monogram of the king - with a crown on both the obverse and reverse.
The first time in our history.
In Edmund Kopicki's Skorowidz attributed to Casimir III the Great, but in the context of research by, among others, Professor Borys Paszkiewicz, based on the style of the crowns, attributed to the mint of Ludwig.
Very rare, and above all beautifully preserved for this variety. With very good detail, in a glassy, beautiful patina.
Bronze, average 16 mm, weight 1.13 g.
