Bulk Challenge Coins Appraisal

Assorted Challenge Coins Lot

This lot consists of four circular challenge coins, likely made of a bronze or brass alloy, exhibiting a uniform diameter and thickness. Each coin features distinct raised relief designs on their visible obverse sides, suggesting precise die-striking or casting as manufacturing methods. The color is a consistent coppery-brown with a subtle satin finish, indicative of a metal that has developed a natural patina or has been treated for an aged appearance. There are no significant visible condition issues such as deep scratches, dings, or areas of heavy wear; the details of the relief designs appear sharp and well-preserved. There's a slight sheen across the surface, possibly from being recently handled or stored in a protective material. One coin, positioned at the top left, displays the phrase "SAVING LIVES BY DESIGN" in an arc around the top edge, with a detailed illustration below it that appears to include industrial or engineering elements, potentially a bridge, structure, or specialized equipment. The coin at the top right features text, partially discernible as "ROADWAY ASSISTANCE" and what looks like a computer keyboard or data input device, suggesting a theme related to technology or infrastructure support. The bottom left coin showcases an emblem with the words "AIR NATIONAL GUARD" in a curved banner along the left side, enclosing a shield-like design with what appears to be a figure or insignia related to aviation or military service. The bottom right coin exhibits a cityscape or architectural skyline, possibly representing an urban area or a specific construction project. The overall quality of craftsmanship appears high, with fine details discernible within the relief. There are no apparent maker's marks or signatures visible on these sides. Given the thematic content, these are likely modern-era challenge coins, typically given to members of an organization, unit, or project team to signify membership, honor achievements, or commemorate events. Their estimated age is likely contemporary, within the last few decades, judging by the themes and clean condition.
