Reference to the historic 1918 airmail stamp

Iconic motif recreated in pure silver

Limited edition for collectors of rare themes

Beginning of an extraordinary collection “ The World’s Most Valuable Stamps”

The first airmail stamp in U.S. history and remains one of the most expensive

and legendary printing errors ever — the airplane was mistakenly printed

upside down. Today, this philatelic rarity continues to inspire collectors around

the globe. Now reimagined as a silver coin, it captivates with its craftsmanship

and symbolism — a tribute not only to a unique stamp but also to an era when the

dream of flight was just beginning to take shape.
