Tiffany & Co 14KT 1/2" gold round lapel pin with a scalloped edge.

AMERICAN is printed around the top and DYEWOOD CO around the bottom. Spanning the diameter is a log. In the center of the pin is a shield with the number 25 on it. The pinback is a J-hook style with a lock. Back is etched with Tiffany & Co 14KT Gold.

I have dated the pin at between 1930-1947 based on a makers mark on the pin and research on The American Dyewood Company.
