I don't know how errors occur with hammered coins, but I think this is what you have. In the first photo, it looks like the tips of the long cross at 3:00 and 6:00, which should be (and are) on the reverse, and between them the letters VND which can be seen in the same place on the reverse. IN the second photo, the legend is disappearing into beading that should be at the rim at 5:00.
Other than this, some groups of letters can be made out, (obverse seems to suggest HENRICVS?), but difficult beyond this.
