I need help with this coin. What is it? How much is it worth?

[24k dreams]

I know it's a German coin and it is silver. Other than that I don't know much about this. It's my dads, he wants to sell it and I wanted to help him. Please help.

Here's a nicer one, so maybe half of what it got, or maybe a bit less. At least with the ID you should be able to figure it out.
