Herion-Werke KG 1938-1978, Fellbach

Hello, I am the owner of this silver medal, but I don't have much information about it. Do you know anything more about that medal? I found some information about that company, but not about the medal. I only found this on eBay https://www.ebay.de/itm/175255448234 , but there isn't much information and I don't even know if it's correct (including information about silver fineness).

I am attaching photos of my coin. If someone is able to put it in the catalog, I agree to the use of my photos, but as a complete novice without knowledge of further information, I do not dare to do it myself.

I know nothing about this object but the hall mark K1000 (no idea what the K really stands for) would indicate that it could be a pure or rather .999 silver. But I always have the information in my head too, that the 1000 was sometimes used for silver plated objects so you will have to make a density test (try to use distilled water a non metal or rubber hook) and see if you get very close to that of silver (10,49 g/cm³).

The weight is approximately 9.78 g

Now you need the volume 😅 or do the specific gravity test I linked above.
