German coin I/D

Maybe Someone can help identify this coin? And value of it.

Please give the measures and the alloy. Then look up what is written on the coinj and you'll find it. I did.

@evo, as sjoelund says, you can see the country name in your first photo (read the lettering around the rim), you can see the denomination in Roman numerals on the same side (look near the crown), and you can see parts of the date.

ON the portrait side, you can see the ruler's name, or at least an abbreviation.

If you type these things into the Numista search field, you will get your answer, and learned how to do the search.

I forgot to send you link with the procedure to follow:
