Small Metal Tags/Jetons/Tokens from LYON France

I had ABSOLUTELY no idea what these metal tags were used for until I did the research.  Each one has been stamped with the same thing. These are Jetons or Business Tokens that generally came with a paper ticket. We listed the matching paper tickets on another listing on our site under ephemera. Some tokens are rare and some aren't. On the NUMERISTA scale for rarety with "0" being least rare and "100" being rare thes scored an "85". Personally I just thought they would look great for a project whether it was scrapbooing or jewelry. I had no idea the rabbit hole of business tokens I would get myself into when I started researching these,
