Nice detail, especially of the reverse, but at 12 o'clock disc abrasion. Possibly a trace of a pendant, although manipulation is not noted (probably manufacturing).
Type with the coat of arms of the Fox under the bust of the king. Coat of arms belonging to Lev Sapieha, Grand Chancellor of Lithuania.
Royal bust with crown decorated with trillium and leaves.
Piece from the collection of Tadeusz Kalkowski with his envelope included.
