Please note that there is no hallmark on the back of the badge. Through my research, I do know some did not have hallmarks; however, I have no history on the item and don’t know if this was issued by the department after retirement or made sometime after. Star measures 3” across. Pin measures about 2 1/4” there is build up in the crevices, oxidation, rubbing, marks and water as photographed. Please examine all photos and reach out with any questions
