Vintage Octagonal Monogrammed Toggle-Back Cufflinks

This is a pair of vintage men's cufflinks featuring a distinctive octagonal (eight-sided) face design. The items appear to be constructed from metal, likely silver-toned or potentially sterling silver, though they exhibit significant surface oxidation and a dark, heavy patina consistent with age and exposure. Each face is intricately engraved with a sophisticated interlocking script monogram, possibly for the initials 'S' or 'J', set against a textured, engine-turned, or frosted background. The attachment mechanisms are standard toggle-back (whale tail) posts, suggesting a mid-20th-century manufacture date, approximately 1940s to 1960s. Physically, the cufflinks show signs of authentic vintage wear including micro-scratching on the high-relief edges and deep tarnish in the recessed areas of the engraving. There are no immediately visible maker's marks or hallmarks in the image, but the quality of the engraving suggests professional craftsmanship. The geometric shape combined with the ornate script provides a classic Art Deco influence, balancing rigid structure with fluid aesthetic details. They are shown resting on a wooden surface, highlighting their relatively small, standard size for dress shirt hardware.
