Hello Caveman,
I think this is a gros of Carol V (1506-1555) struck between 1521-1555 (second emission).
van Gelder en Hoc 193-1b. The coin has no date.
The text is CAROLUS D G ROM IMP HIS REX D(VX) B(R) (Z)
on both sides. The coin has on the first picture, a lis in the centre, so the mintplace is Brugge.
This means also that the end of the legend is not DVX BR(Duce of Brabant) , but C(omes) F(land), since Brugge is in Flanders.
Nice quality, congratulations on this find

Nico.
