Yesterday I started researching one interesting coin (which I do not posses yet). There is a big letter: H in the middle of the coin, and on the reverse some letters similar of that of the Polish-Lithuanian commonwealth or Holland. Very strange indeed. But nevertheless, I have some theories that this coin is neither Polish-lithuanian or Holland. I think that it's either some coinage of Henry III or one of the following:
I have doubts about the letter H
If you turn that picture 180° it looks like a castle gate or something like that
Your coin gives me a mediëval feeling (1200-1500)
But I can be wrong, just guessing
Nevertheless, it is a nice coin
Thanks ! well, the search continues, all these countries are very similar, but this remains a mystery. Damn, this is a hard one Brittany is as close as they get as well....

Italy, Lucca, Henry III-V, 1039-1125, AR denaro. The letters at reverse center are LVCA (Image below courtesy CNG). This type (or similar) is in the Numista catalog, though you'd never know it from the photo.
