This coin is in rather poor condition. You can see that something had probably been soldered onto the back of the coin, and then removed. HOWEVER, this is a very unusual, and probably very valuable coin. It is believed that this coin is from 1879 because of the inscription of MDCCCLXXXIX on the coin, which translates to: MDCCCLXXIX = M (1000) + D (500) + C (100) + C (100) + C (100) + L (50) + X (10) + X (10) − I (1) + X (10) = 1879. According to AI, this is the year of the Silver Wedding Anniversary of AUSTRIA King FRANZ JOSEPH I & ELISABETH, and this coin was minted to celebrate that occasion.
