Martin Marietta Aerospace Challenge Coin or Medallion

This item is a circular, cast metal medallion or challenge coin, likely made of brass or bronze, given its distinctive golden-brown hue and prominent patina. The coin features a raised, three-dimensional design on its obverse, depicting a figure in what appears to be an early spacesuit or jetpack, hovering above a stylized winged emblem that could represent an aircraft or an abstract symbol of flight. The figure is detailed with visible lines suggesting clothing folds and equipment. Surrounding the central image, along the outer edge, is an inscription in raised capital letters that reads, 'Martin Marietta Aerospace - Masterminding Tomorrow's Technology'. The lettering is clear and well-defined, indicating a high-quality strike or cast. The surface of the coin exhibits a uniform, aged patina, giving it an antique or vintage appearance. There are no obvious signs of significant damage such as deep scratches, dents, or corrosion, although the image resolution does not allow for a microscopic examination of wear. The overall craftsmanship appears solid, suggesting it was produced as a commemorative or award piece. The style is industrial and commemorative, reflecting the aerospace theme. Given the 'Martin Marietta' inscription, this item dates to between 1961 (when Martin and Marietta merged) and 1995 (when it merged with Lockheed). This falls within the latter half of the 20th century. The consistent patina across the surface indicates it has likely been handled but overall well-preserved.
