Nickel silver shield-form badge finely engraved “DEPUTY / CHIEF / SHERIFF” in ornate gothic lettering, bordered with hand-engraved scrollwork. The reverse bears a horizontal pin clasp and is maker-stamped: Nathan Joseph / San Francisco, Cal. The title “Deputy Chief Sheriff” likely referred to a senior ranking officer serving directly under the elected County Sheriff, typically overseeing field operations, jail administration, or departmental divisions. In the case of San Francisco, the designation is especially significant — the city and county are one unified jurisdiction. The San Francisco Sheriff’s Department, one of the oldest in California, was responsible for civil enforcement, jails, and courtroom security, while the police department handled patrol and criminal investigations. Nathan Joseph was a renowned San Francisco jeweler and badge maker active from the late 19th century through the early 20th century. His firm supplied custom engraved insignia to California law enforcement agencies, including sheriff’s offices and municipal police departments. Joseph’s badges are recognized for their craftsmanship, quality materials, and detailed engraving. Dimensions: 2 1/2 x 2 1/4 in. Pickup & Shipping: Free Sacramento pickup.
