2018 Silver World War I Centennial Coin and Air Service Medal Proof Set

The 2018 Silver World War I Centennial Coin and Coast Guard Medal Proof Set commemorates the vital role of the U.S. Coast Guard during the Great War with a refined two-piece presentation. The centerpiece is a one-ounce, .999 fine silver proof coin featuring the U.S. Mint’s deep-cameo finish: frosted devices contrast against mirror-like fields to bring every detail to life. The obverse bears a modern Liberty portrait symbolizing freedom, while the reverse depicts a Coast Guard cutter steaming through choppy seas—escort and rescue missions rendered in striking relief to honor the Coast Guard’s wartime service.

Accompanying the proof coin is the matching Coast Guard Medal, struck in antiqued bronze and showcasing a vigilant cutter officer standing at the rail, gaze fixed on the horizon in defense of Allied convoys. Both pieces are housed in the original government packaging (OGP), complete with a numbered Certificate of Authenticity. This proof set blends numismatic artistry with historical tribute, making it an essential addition for collectors of military commemoratives and modern proof coinage.
