I would love to know more about this concho belt which my grandmother picked up on a trip many many years ago. She was born in 1900 if that gives you some idea : ) Here are a few pictures – including one of the hallmark which looks like a fish. Thanks so much for any thoughts and perhaps a ballpark range of value.
Your belt is beautiful and definitely looks to have some age. A close up of the silver and stamp work would help. I find the rivet interesting. Do you remember this belt from when you were young? If so do you remember the leather and rivet? I couldn’t find any hallmark like this, but that is definitely not uncommon. I think of belts like this being Navajo made, and of course those of us who live here in the four corners know we are not fish and water people. I imagine the mark might be for a smith who is Christian? Please provide that closeup and I will give you a ballpark value.
