Delmenhorst medals - anyone with information about them?

A million years ago (or so it seems), I bought from my local coin dealer in Springfield IL two 0.986 silver medals commemorating the 600th anniversary of Delmenhorst becoming an independent city. One is about the size of a US quarter, the other a half dollar.
Delmenhorst is a small city in NW Germany, with less than 100,000 residents, located near Bremen. Interestingly, both medals have one side depicting a view of the city and its castle in 1671 in proof, while the other side has the city seal in mint state.
I have not been able to find any information about these: mintages, past sales, etc.
Unfortunately, I am utterly clueless in being able to post photos of these medals, so if anyone could educate me on that subject, I will try to post some photos I took.
Thanks!
