Hi folks,
Well, first of all, please forgive me for asking my question in English but I'm French and unfortunately I've never had the opportunity to learn German.
I'm currently detecting in the south of Belgium but, few years ago I used to play with my XP Deus in Liège - Lüttich, 20km away from the German border.
I once found found the relic of a silver coin on which I managed to read "fürst" (so I guessed it was German) between to circles of dots. It weighs 0,95g. Unfortunately I wasn't able to gather more informations about this coin.
I recently found it back in my drawer and, even if it's in a really poor state, I guess that maybe you will be able to help me identify it.
Thanks in advance for your help.
Jean
