May we see a picture of the back please?
Hi Gabriel; Since it is not American I can't help you on this other than to ay that it is not silver though it may be siilver gilted ok. Second is that I believe from it's looks that it is Modern Button from 1920 to 1960's ok. Sorry I an't nail it down better for you. Nice Find. See you on the Trails. PEACE:RONB
