On the obverse a crowned small letter K with rings on the sides, all in a decorative cartouche, on the reverse a crown with rings on the sides, all in a decorative cartouche. Ruthenian coins were the first Polish copper coins minted by Casimir the Great, Władysław Opolczyk and Ludwik Andegawenski and until 1650 remained the only money minted in copper in the Polish lands. Minted with care, in a non-precious metal and having a low circulation value, the pieces preserved to this day are usually in poor condition and obtaining a well-preserved piece is difficult. Rare.
