Circulating, fully legible example of the penultimate vintage of the Bydgoszcz sixers.
Type I bust, coat of arms shields with volutes on the sides, two rosettes next to the crown, a flower between the shields.
The 1667 Bydgoszcz sixpacks form a very diverse group of coins. The differences on the reverse concern the shape of the shields of arms and the decorations between them and also next to the crown. The differences on the obverse concern only the bust, which can be attributed to several types.
