A nice piece. Typical sheet flaws for Bydgoszcz issues. Well-preserved mint luster.
Type VI bust - a classic Bydgoszcz portrait used during A. Tymf's lease, the reverse also in the typical style characteristic of sixpences from A. Tymf's lease, but the reverse bears the T-T markings of the previous tenant Tomasz Tymf.
The coin is illustrated in the catalog of L. Ciura.
Note: the book is not the subject of the auction.
