International Union of Elevator Constructors Lapel Pins (unverified)

This lot features four metallic lapel pins displayed on a wooden surface, with one piece partially enclosed in a transparent plastic bag. Three of the pins are identical circular insignia featuring a gold-toned border with decorative laurel wreath or ridged detailing, a deep blue enamel outer ring bearing the legible text "INTERNATIONAL UNION OF ELEVATOR CONSTRUCTORS", a central white and gold rayed background depicting an elevator shaft graphic, and the number "25" marked at the bottom indicating a 25-year service milestone. The fourth pin, located inside the plastic bag, is a white and silver-toned circular commemorative piece featuring the text "100 YEARS 1899 1999", "LOCAL 4 BOSTON", and "I.U.E.C.", along with a central graphic illustration of an elevator worker or mechanic. The physical condition appears generally well-preserved with intact enamel work and minimal surface wear, though all items remain unauthenticated in terms of exact precious metal purity or manufacturer origin. The identification is based entirely on the legible text and iconography visible on the face of the pins. These pieces are consistent with mid-to-late 20th-century union memorabilia and labor organization awards.

Based on what I can see in the provided image, this lot consists of four metallic lapel pins associated with the International Union of Elevator Constructors, including three 25-year service pins and one Local 4 Boston centennial commemorative piece. Based on the assumed attribution to mid-to-late 20th-century union memorabilia, comparable items of this type typically trade in the $60 to $120 range as a collective lot, driven primarily by labor history collector demand and niche fraternal organization collecting. However, I can't verify from a photo whether these pins contain any precious metals, specific manufacturer hallmarks, or if they are period-correct pieces rather than later commemorative replicas. Physical inspection would need to be conducted to confirm the material composition, pinback hardware integrity, and enamel quality. If these pieces were determined to be modern reproductions, fantasy items, or copies rather than period-issued union awards, the value would likely drop significantly to around $15 to $30 for the lot. To establish a more precise valuation and confirm authenticity, one would need in-person examination by a militaria or labor memorabilia specialist, along with potential metal composition testing.
