I had trouble understanding the design of this Lithuania 1 schilling 1664, until I realized that the coin had been struck twice, with nearly a 180 degree rotation between strikes. You can see the knight's upraised sword at 11 o'clock and again at 3 o'clock.
The first strike was off-center; the date is partially visible at the edge of the coin.
On the obverse, AN of IOAN is clearly visible on both sides of the coin.
