Vintage Monogrammed 'LE' Silver-Tone Lapel Pin or Button

This is a small, circular commemorative or monogrammed pin featuring the initials 'LE' in a serif-style block font. The item is approximately 1.5 centimeters in diameter, categorized by a scalloped or gear-like decorative edge that mimics the shape of a crown or a bottle cap. The construction consists of a raised silver-tone border and central lettering set against a dark, possibly oxidized or enameled black recessed background, which provides a high-contrast visual effect. The metal appears to be a base alloy with a silver plating, given the visible wear and darkening in the crevices. In terms of condition, the item shows significant signs of age and handled use; there is visible tarnishing on the metal surfaces, a heavy patina within the textured borders, and some surface scratches on the central face. No specific maker's marks are visible on the front, but the design style is consistent with mid-20th-century membership pins, service awards, or personalized haberdashery accessories. The craftsmanship is utilitarian but precise, with even spacing in the scalloped edge. While its specific origin (corporate, fraternal, or personal) is unknown, the piece serves as a classic example of mid-century personal identifiers commonly used on lapels or hats.
