This very arty pin is made of sterling silver with blackened portions. It is from 1930-1940 . The back side has many back stamps from .925- Mexico-Taxco and an eagle with # 2 or 3-hard to read and the makers name. The pin is simply made and has a great look on. It is in excellent condition . I have not polished it as many of my customers prefer to use their own products. 1/2"- 3 1/4"
