The sixpence is a denomination that only gains prominence in the time of Jan Kazimierz in times of war. After small issues in 1650, it does not return until during the Deluge, in 1656, when the issue enacted by the king is started by Lviv, and minted in occupied Lviv by the Swedes. Polish Kraków sixpences are not minted until a year after the city is recaptured, when the lease over the mint is taken over by the famous Boratini.
A very rare vintage of Jan Kazimierz's sixpences, known from two varieties.
The present piece is the variety with the date in the rim. A characteristic feature of these sixpences is also the lack of denomination numerals.
A typologically sought-after, very rare issue.
