Silver-Tone Shell Motif Lapel Pin or Cufflink

This item is a small, silver-tone decorative accessory featuring a classic scalloped shell motif, likely a lapel pin, tie tack, or a single cufflink. Physically, the piece displays a high-polish metallic finish, giving it a bright, reflective appearance characteristic of chrome plating, rhodium plating, or sterling silver. The construction involves a cast metal front shaped into a fan-like shell with distinct vertical ribbing and a rounded lower hinge area. On the reverse side, a central post is visible, suggesting it would be secured with a butterfly clutch or similar friction fastening, common for pins of the mid-to-late 20th century. The condition appears fair to good; there is visible surface wear, minor scratches, and some potential oxidation or dulling of the finish in the recessed grooves of the shell. No specific maker's marks, hallmarks, or purity stamps are visible in the current view, which often indicates a mass-produced costume jewelry piece rather than fine jewelry. The style is classic and maritime-inspired, a popular theme in accessory design from the 1960s through the 1980s. The craftsmanship is standard for utilitarian decorative hardware, with the molded details being clear but not exceptionally fine-edged.
