I have no clue what it is and no matter how much I look online I can't find anything. I'm beginning to think I was scammed or something.
What you have is a veteran's association medal to commemorate the 25th anniversary of the Franco-Prussian War. It was issued by the Veteran's Corps of Berlin in 1895. It is not a government issued medal.
Glad to help. There is a fairly complete set of photos of official issue medals in the GDC Reference Gallery under Imperial Orders & Medals and Imperial Combat Badges.
