A rare coin from the Mazovia area.
Chipped in half.
The issue about which Stronczynski wrote as follows: "the coins of this Siemowit are thin and made of quite licentious silver.... In excavations only found next to these Wladyslaw money. They do not belong to the common ones, and quite a high price, especially in good specimens which are not easy to find.".
Obverse: letter S in a pearl border, in the rim: DVCIS ◦ SE[MOVIT]I +.
Reverse: heraldic eagle, in the rim: [COIN PLOCEN +].
