Help I/D silver star

Hello everyone I have what I believe to be a Navajo made Cochise County pin that I Believe would have been sold in a tour shop but was hoping maybe someone could Give me some Information on it or better yet find another one somewhere on the internet as a Example I have searched and searched and haven’t found another 1 and I know the people here always seem to find what I can’t . I tested it and it tests as silver thanks once again Matt.

 

The marks are of course ED and the other looks like a Scorpion to me but that’s my guess

 

Tourist souvenir possibly with replaced pin hardware.

 

The one bit of scratches looks kind of like “Cate”. It’s cool, I want one.

 

Thanks dagger for your reply now that you said “cate”I would say that’s what it is didn’t notice than good eye.
