VINTAGE Mexico 925SS 3-d Bear Charm On Link Chain W/Toggle Clasp, EUC J#77

3-d Bear Charm on link Chain with toggle clasp. 7.5" long, 1 1/8" charm. All Hallmarked 925 in Ring bear is on and on toggle. one I had to get my Jeweler's Loupe out because it is small, and the word Mexico is hallmarked. There is some thing else inside the ring but it is so small I could not read even with loupe. Dont know if this is Zuni, but it is identical to ones found in my research. The only hallmarks I could read are the 925 and Mexico.
