Medal ice trapped

[francantolin]

Good day dear members

I try this one:
I was walking last week-end in the Alps on a glacier when I found this medal under the ice.
a medal, not a coin, flat on the reverse side so I don't think it's really medieval😅.

The engravings king/rider with a sword with a devil/someone under ? and the w signs ?? reminds me something but i can not fix it.
