This is not only a beautifully preserved sixpence, but also a very rare variety.
In the specialized catalog of John III Sobieski's sixpences, it was defined by the highest degree of rarity, and is further illustrated by this piece.
It is distinguished by the jewel arrangement of the 5/5 crown and the lack of rivets in the cuirass fittings.
An early type for this vintage - with the coat of arms of Leliwa, Grand Treasurer of the Crown Jan Andrzej Morsztyn.
Beautiful luster. The whole in a light, natural patina falling into celadon.
