Silver medal table tennis

This is apparently silevr meddal, for some table tennis tournament.I have been told that medal.l is solid silver?

If someone knows anything more about this medal, and if medals like this have been made from solid silver, or it's usually just silver plated?

There is nothing encrypted on back or side.

Lots of good info here: https://treasurepursuits.com/how-to-test-silver/

There is a good app that will detect the ringing of silver for you, however I forget the name at the moment.
