Occult or Rosicrucian Copper Sigil Pendant

This is a circular, talismanic pendant likely constructed from a base of copper or a copper-alloy such as bronze. The item features a flat, disc-shaped body with a single integrated bail attached to a simple jump ring at the top. The central design is rendered in a lighter, brass-toned metal, possibly as an inlay or through selective plating/cleaning of the raised relief. The iconography consists of a central vertical staff or sigil topped with a flared cross, an 'S' shape entwined around the center, and a horizontal bar at the base. It is flanked by two smaller crosses pattée on either side. These symbols are highly characteristic of esoteric, occult, or fringe religious groups, specifically evoking Rosicrucian or Hermetic imagery. The surface shows a deep, dark brown oxidation and patina, consistent with aged copper, with visible surface pits and granular wear suggesting significant age or exposure to the elements. There is no visible maker's mark or hallmark on the obverse face. The craftsmanship appears to be folk-art or small-batch production rather than high-end jewelry, given the slightly irregular edges of the central symbols. The piece likely dates from the late 19th to the mid-20th century, a period of heightened interest in Western esotericism.
