Late Sigismund III sixpences are coins minted on a mass scale, and although they have survived to our time in numerous pieces, they are very difficult to obtain in mint condition.
A rarer variant with the Half-Kosic coat of arms (interesting in its typeface - by one numismatist this type was called a "devil") in the shield, under the bust of the king.
A variant with an Arabic numeral in the date.
