Purchased in a lot of jewelry recently. Trying to figure out the hallmark, maker. Thanks for the welcome Tah.
@LUCKYSTIKE Hi & Welcome. That’s a terrific Big Horn Ram pin. I checked my Bille Hougart’s book on “Native American and Southwestern Silver Hallmarks” for that hallmark but, unfortunately, I don’t see it. It can be challenging to identify single letter hallmarks. Have you tried Google Lens? Also, there’s an online hallmarks resource that could be helpful: https://www.art-amerindien.com
Hi Patina, yes, checked all online and reference books. Came up blank myself. Thank you for your input.
