This medal was the 37th official issue of the American Numismatic Society. It commemorates the flight of the king and queen of Belgium to England on the occasion of King George and Queen Mary's silver anniversary. The celebrations took place in London on July 6th, 1918.
The latin quote on the obverse is an abbreviation from the opening paragraph of Caesar's Commentaries on the Gallic War—"(Horum eorum) fortissimi sunt Belgae", meaning "The bravest of these are the Belgians." It is easy to forget that the year was 1918 and World War I was still being fought in Europe. Flying across the Channel by itself was not yet a common endeavor, but doing it during an active war was certainly a display of courage that cold not help but boost morale.
The medal measures 63.8mm (2.5in) and was struck by the Medallic Art Company of New York in bronze and silver. As with all early ANS medals, the mintage is very low; 1 medal was struck in gold, only 97 medals were struck in silver and 136 in bronze. Originally, the silver medals were sold for $10 and the bronze medals for $5.
