MEXICO CHARLES III HALF REAL 1780 IN FAIR/GOOD CONDITION. A GERMAN MEDAL; WILHELM DEUTSCHER KAISER ZUR ERINNERUNG AN DAS KAISER-MANOVER 1885
I can't tell from your picture, but you might want to check the 1/2 reale for a 80/79 overdate. That would increase its value.
Then it would be English. It's Hannover in German. But this medal actually says Manöver which means a military "maneuver" or "manoeuvre" depending on one's orthographical preferences ... Christian
