Deeply minted, clearly glossy. A very nice piece, especially for this rare vintage.
This is the last year of Sobieski's Kraków sixpences. With their characteristic letters: C of the Kraków mint and B of the mint's lessee Gotfried Bartsch. Minted in the year when the Sejm in Warsaw resolves to close the mints in the Crown.
Variety with a narrow bust of the king and a wide crown on the reverse.
