For your consideration is this interesting sterling silver pin. Very ornate with a center mushroom and vines and applied shapes against an oxidized edge background. I always try to look for interesting unique items in my travels and this fits the bill and I can't find anything like it. Purchased form a jeweler and tested by both of us and guaranteed as sterling silver. I found it odd that it does not have a sterling mark and would have dated it earlier but the locking pin back mechanism puts it at 1920s earliest. It has patina and age.
It measures 1 and 7/8 inches by 1 and 3/8 inches.
Excellent functioning condition. One bottom ball is a little irregular but this does appear to be part of the making.
