America's 250th Anniversary challenge coins honor 250 years of liberty. Expertly crafted from solid metal with 24K-gold plating, the coins showcase deeply detailed, raised-relief imagery. Each coin commemorates a different milestone in America's history, hand-enameled by master artisans. The backs feature a majestic American Eagle clutching two crossed rifles. Measuring two inches in diameter, each coin arrives secured in a crystal-clear capsule.
