:::::: Is the edge hallmarked? Sometimes these medals have hallmarks along the edge of the rim. ::::::: Strange I see the similar coin with the bull and the 999 hallmark but I can't find this coin at all anywhere ::

Aguest hello no the edge is clear only this 10000 mark . by the way i couldn't find anything in internet with google lens program too so i decided to ask here on this site. also on the silver reagent it becomes red ( i was told thats its pure silver )

:::::: It must be the same company as the other coin with the bull on it, the details are similar and there is a German pronunciation symbol Umlaut (2 dots) over the "A" just like the other coin so I am assuming the mint that struck these coins/medals is in Germany. :::::

:::::: I've seen 900/1000 and 925/1000 but I've never seen 1000 just by itself. ::::::

::::::: Really mysterious that this is the only example of this coin using google image search, and also the mysterious 1000 number :::::::
