Good Luck. they are actually so rare and obscure that when they appear, they are not a lot of money ( so far). Of course now that we have discussed them in an open forum.........
I speculate that these medals were awarded to Patriots in the late 1940s/early 1950s and that they were given primarily to those Ethiopian Patriots who were active in the secret underground Nationalist resistance societies like the famous intellectual Black Lion Group or the infamous Omoro Resistance Army.
The Italians occupied the major towns and cities of Ethiopia and unlike the countryside, which was constantly fought over throughout the occupation, the towns were pretty dangerous places to be in. Most of the major towns had bobbed wire fences and concrete pillboxes around them. After the attempted assassination of Graziano, the Black Shirt militias went on the rampage in Addis and many other places, killing thousands of innocents indiscriminately. Thousands of other intellectuals/elite /nobility were sent to Italy for Acculturation'.....e.g. Hostages. The underground in the cities were very brave people indeed and many were women.
