A very nice, glossy piece.
Type III bust, Slepowron coat of arms in a circular border, shields of arms straight. The last digit of the date corrected from 0 to 1. This subtle interference of the stamp engraver finds its analogy in Cracow boratines on which such correction is very common. On the sixpences this procedure is less noticeable, but also less common.
The coin illustrated in the catalog of L. Ciura.
Note: the book is not the subject of the auction.
