My first thought with that style and central mess would be a weisspfennig of Bohemia. Apparently the visible legend is consistent with
a Bohemian weisspfennig of Vladislaus II, but if so it must be a variant with much more modern lettering than the Numista example.
EDIT: oh,
here's one. I think I can see a faint image of the crown and W on the other side so that has to be a match.
(The legend is still a little off but there are probably other variants.)
