A rare type of coin with the Swan coat of arms (of Andrzej Zawisza - Grand Treasurer of Lithuania) and the mint mark hook on the reverse.
Very rare vintage, underestimated in the literature.
Extremely rare, not described in specialized catalogs, obverse obverse legend: separated letters D - G under the bust of the king.
Iger and Ivanauskas do not note such a variant.
A great class, unique, mint piece, with sharp luster and exquisitely preserved details.
For the best collections!
