Just returned home from an exhausting day of helping my mother clean up the attic in the old family house. And while doing so, I found this little gem amongst some old shit:
My initial guess was that it belonged to my father, and after asking him he confirmed it. Furthermore, he was more than happy to gift it to me!
Now, I am too exhausted to do any research about them but I think none of them is made of silver, which is a bummer. However, they are pretty old, as the label reads, the oldest one is from 1882. And they are also in pretty good condition. Not perfect, but pretty good.
My guess is there is some collectors value laying there And that coin in the middle is made of copper and imo quite sexy! Even if they don't have much value, it's neat to own a piece of history :)
I'll do some research on them and return with more photos and info about them one of these days. Also tagging my friend 
Stay tuned!
