Do you recognize the
mintmark? Because the
mintmark uses a rune, which was banned in
Hungary by this point, I
had to wonder if it really was from Sigismund, or was an
imitative from a neighbour. Essentially, the
cross and the rune don't go together - but my knowledge of this is
still very limited. I know many of the basics, but none of the many exceptions that make this period so very interesting.
