Military Medical Commemorative Challenge Coin or Medallion

This is a circular, cast bronze or brass alloy medallion featuring a high-relief (bas-relief) sculptural scene centered on military medicine. The object measures approximately 1.5 to 2 inches in diameter and displays a warm, golden-brown patina consistent with aged copper-based alloys. The composition depicts three figures in field uniforms tending to a fallen casualty, set against a background featuring a transport helicopter (likely a UH-1 Iroquois 'Huey' or similar medical evacuation aircraft) and a waving American flag with stars and stripes. At the bottom of the scene, a large 'Lamp of Knowledge' or Florence Nightingale lamp rests upon a bed of laurel leaves, symbolizing nursing and medical care. A single small hole is drilled at the top center, suggesting it was intended to be worn as a pendant or hung as an ornament. The craftsmanship shows moderate detail in the figures and background elements, typical of late 20th-century commemorative numismatic art (circa 1980s-2000s). The surface shows minor micro-scratches and slight darkening in the recessed areas, which enhances the visual depth of the relief. There are no clearly visible maker's marks or serial numbers on the obverse side, indicating a mass-produced but specialized commemorative piece for veterans or medical personnel.
