Help Identifying this Pin that I stumbled across and looked intresting

Please take a look at these photos and help me identify this piece. there are no hallmarks that i can find just the sterling mark on the back. Would like to know the age and tribe if possible. also if possible a estimated value

Hello, thanks for sharing. I don’t believe this to be Native American made. Also, from the picture the piece doesn’t appear to be sterling, maybe have it tested. Sorry I couldn’t be more help, thanks for sharing.
