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 begins in Lviv, and is minted in occupied Krakow 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 (here deficient). However, features such as the letters TLB under the stylized shields of Poland and Lithuania are present only in this vintage.
An interesting feature of these sixpences is also the absence of the denomination numeral.
A typologically sought-after, very rare issue.
