3.25" vintage butterfly shaped stick pin, a type of jewelry typically used to secure neckties, cravats, or lapel hat pin with a polished finish.

The construction reveals that the pin shaft is soldered directly to the butterfly finding rather than stamped with metal purity markings (like "14K" or "925") or maker marks (like "Monet" or "Napier"). Because it is an unbranded base-metal piece with an enameled front, its resale value typically averages $5 to $12 USD as a vintage accessory
