Lorrain, Duchy - 1/2 groschen?

Will appreciate help with identification.

I got this about 10 years back from my dad, who thought it might interest me in French states like it does in German. I am now trying to sort this out and need some expert help as the coin is defined in catalog but without the necessary details. This is not a Charles & Nicole (1624-25) groschen as listed as the legends are flipped with the images - reverse shows crowned eagle is paired with MONETA.NOVA NANCEI. G(or C) VSA and obverse shows small Lorrain shield but no crosses and is paired with the legend of which the only readable part is LOTH .B. DVX. Dad identified is as Charles & Nicole 1624-25 but I am not sure as the text before LOTH appear too short. I attach scans and pictures to help identify. Billon, size is approximately 16-18 mm and weight is 0.8 gr.

I'd rather bet : ½ Groschen - Henri I

I saw it too of course, but legend is very different than what is shown on the picture. The legend on the Henri I spells NANCEII.CV while the image shows that the legend ends at II. and no further letters, just the crown on imperial eagle. Maybe wrong picture with the right coin...Will keep searching as I have a dozen other Lorrain coins of the same period and condition to re-verify...

The lettering so far >


MONETA NOVA NANCEI CVSA
Moneta Nova Nancei Cusa
New money minted in Nancy
Alerion (heraldic bird) with outstretched wings,
crowned with a ducal crown - cutting the legend above.


............ LOTH B DVX
............ Lotharingiae Barri Dux
............ Duke of Lorraine and Bar
A central single shield containing the merged shields of Lorraine
and Bar under a ducal crown - cutting the legend above.

Obverse was easier; can just about make out a G on reverse, so there is
probably a D before it also. Most coins I have seen have HENRI lettering -
but, they are with a double (not single) shield - and can not see anyway
where that would fit, though maybe the H would be next to the crown.

Magic! Many thanks Zac. I think we can pretty much exclude the original assumption that it was Charles IV and Nicole, their half groschen was similar size, 7 gr but a single shield as noted in catalog (I've submitted a change to the entry as well to reflect corrections in the legend and additional pictures also posted here.
