A nice, well struck piece.
Type I bust, coat of arms shields that are hybrids between engravers' styles (including a different Pogo). Rosettes next to the crown and between the shields in a different form.
The coin illustrated in the catalog of L. Ciura.
Note: the book is not the subject of the auction.
The 1667 Bydgoszcz sixpences 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 next to the crown. Differences on the obverse concern only the bust, which can be attributed to several types.
