Patric, I think that's just patina. Now why that happens so quickly and so darkly in your case is unknown to me. Some sort perhaps chemicals in the air and humidity perhaps are the culprit? Or possibly a reaction to something in the cloth they are mounted on?
I'd bet dollars to doughnuts that if you took some soapy water and a soft cloth (microfibre, for it's non-scratching proprties) to them all that black would come off.
I have a few silver medals in my collection and some do have a very dark patina. I quite like them like that.
I think you're in no great danger at all but thanks for bring to light a valuable topic.
